When it comes to jealous within a relationship, things can get messy. There are times when jealous is normal and then there are times it is taken too far. When the big green jealousy monster takes over a partner it can mean the end to a relationship. It's difficult to concentrate on the happiness you share with your partner when one of you can't trust you simply due to their own insecurities. Sure, it's not always because of insecurities. Sometimes the lore goes a lot deeper with two people. But in most cases, jealous arises from some sort of past trauma in another that they project. 

 

But we're not trying to dissect anyone's psyches here. We're just sharing a story about a jealous girlfriend who was way out of line. Most people know that it's a relationship "green flag" when you find a man who has a healthy relationship with their sister. In this case, however, the girlfriend lost her cool. The siblings were fraternal twins, one was a guy and the other was a girl. They were close siblings, friendly even, but in no way "attached at the hip"—they both very much led their own separate lives. But the twin brother's girlfriend still could not stand to see "her man" spending time with another woman, even if that woman was his literal twin sister…

    What would you do if your brother's new girlfriend was constantly disrespectful to you and never even attempted to befriend you. Would you just sit back and let your brother endure that, or would you say something? This Redditor couldn't take it anymore after her twin brother's gf showed up unannounced and then kept acting cold and snooty towards her for playing video games with her brother when she just appeared at their door. So she asked her what her problem was…

  • "AITA for telling my brothers girlfriend that she's weird as ***k?"

    I (F19) and my twin brother have what I would consider a normal Brother, Sister relationship. We both still live at home with our parents. And have similar hobbies. We're not attached at the hip or anything like that, but when both chilling at home we'll often play videogames together or do something we both enjoy,

  • for example we both like those intricate lego sets and will help each other build them and stuff while we just chat about sh. But we have separate lives and do different things too.

  • My brother now has a girlfriend, which is great, I'm happy for him, I myself have a boyfriend who I've been with for the last year or so. My brother has been with his girlfriend for the last couple of months. Whenever my boyfriend comes over, my brother is kind to him and they really get along, so they've become friends which is nice, but then me and my boyfriend will go and do things,

  • its not like my brorher is some third wheel in my relationship, like I said, we have separate lives, but its nice that my boyfriend and him get along. And id love to do the same with his girlfriend but she just DOESN'T like me. I try. But I get nothing from her. And its not a case of her being shy or anything. There's tension there for some reason, I can feel it, though I try to push it aside and be nice to her, it's very clear she has no interest in being my friend or even talking to me.

  • She turned up at our house yesterday, my brother wasn't actually expecting her or anything but he invited her in. We were in the middle of a game thing that wouldn't take much longer so he said "I'll just finish this with (sis) and then we can go chill or do something." She rolled her eyes slightly and sat down on the sofa next to him in the living room while we finished up doing this two player thing. When we

  • were done (like not even 10 minutes later,) he handed me the other controller and she side eyed me and said "finally." So I just decided to say something. I'll literally write how the conversation went.
    via Sea_Phase_9704
  • Me: Do you have some kind of problem with me? Her: No? Me: Seems like you do, why did you side eye then? And why are you always so weird with me? Her: You two are always together. It's weird.

  • Me: (looks at my BROTHER, then back at her) We're actually not, believe it or not, we have our own lives. Her: Always seems like you're together, all the time. My brother: (at her, uncomfortable by this interaction) Babe..

  • Me: He's my brother, we live in the same house (laughs) Her: (gets annoyed that I laughed) Whatever, it's weird. Me: No, YOU'RE f*ckin weird (turns away to boot up another game to play myself) Her: (storms off upstairs) My Brother: (follows her)

  • I didn't see them for another few hours then they went out, he stayed at her place that night. Today he came home, and I wouldn't say he was annoyed at me, but he let me know that his girlfriend was upset that I called her weird. And feels like she can't come over here anymore. (Which is really dramatic tbh.) I explained to him that she IS weird, for whatever weird problem she seems to have with me and him, I

  • asked him "Do you ever see my boyfriend getting weird about you and me?" He said No, and that I have a point. I told him she treats me like I'm some kind of "threat" and that's WEIRD! I've been nothing but nice to her and she gives me nothing back. He said he'd noticed that.

  • I told him his relationships are none of my business, but shes weird as f for the way she is with me. But I told him I'd be willing to talk to her, or maybe he should, to see why she's like this. I don't know what her problem is. 1: So WITA in that situation?

  • quizzicalturnip NTAH. She's jealous of his sibling. Is she jealous of your mother, too? Is any woman allowed to talk to him? If he stays with her, he's so screwed. She's bat sh crazy.

  • xJewelVibe It really seems she's insecure and projecting that onto you. If she's jealous of a sibling, who knows where it'll loop. Your brother should be careful about staying with someone so controlling. NTA

  • Vegetable_Storage_42 My brother had a girlfriend like this. She hated it when he would talk to me if she was at our house and would always interrupt to put his attention back on her. He was in my wedding and wearing a tux so she wore a white dress and tried to get my photographer to take a bunch of pictures of them. He went on to marry her. Then he divorced her and was happy again. OP is NTA and should encourage her brother to move on because it's cheaper than paying for a wedding and a divorce

  • asdrunkasdrunkcanbe It's surprisingly common for super insecure people to be jealous of their partners' family members. This is especially the case when their own family isn't very close and they don't have any opposite-s siblings. It's a level of emotional closeness that they're unfamiliar with, so they completely misread it as romantic attachment. In effect, they want to absolutely be the dominant/only member of the opposite s that their partner has an emotional closeness to, and a sibling or

  • Parents aren't usually seen as a threat because the jealous person still has a frame of reference for a parent-child relationship. Some people though...yes, get jealous when a partner is very close to their parents. They believe that they should now be performing that role in their partner's life and the parent should stand aside.

  • Alice Jewel1_ She was out of line for acting like your normal sibling relationship is some kind of problem. It's weird that she feels threatened by you just spending time with your brother in your own home. You didn't say anything out of line she kept pushing, and you just called it like it is. If she can't handle being around you because of that, that's on her.

  • Caspian4136 ΝΤΑ She needed to be called out on her bulls. Clearly she's jealous that you and your TWIN BROTHER are so close. Like it's bad to be close with your sibling? No doubt he got an earful from her, but at least he's noticed how she acts. Hopefully he smartens up and it doesn't last that much longer. She'll do whatever she can to drive a wedge between you two, and probably the rest of the family. She's the type that needs constant attention.

  • trayC-lou She's jealous, basically because your a female twin, if you were a guy there'd be no issue, but yes she is fkin weird, creepy & crazy that she clearly feels threatened by the fact your female. You said your piece so personally I think it's up to your bro to stand his ground and sort this out and tell her that her attitude to you ain't nice or justified
