Your siblings are supposed to be the people who always have your back. They are supposed to protect you from anyone else, to defend you, and to keep you safe. Sure, you may fight over silly things, you are also each other's harshest critics, but nothing should ever come in between you; that is what family is all about.

To be betrayed by a sibling you always thought you could count on must be life-shattering. Not only because it ruins your relationship with them, but also because it will forever change your family dynamics, and there is nothing you can do about it. Your parents will be forced to somehow pick a side, or at least split themselves up between the two of you, and it will never feel complete again. 

That is what is currently happening to the family in the story below. When their 17-year-old son found out that his girlfriend had cheated on him with his 16-year-old brother, his relationship with his family forever changed. Especially when it was revealed that the girlfriend is actually pregnant with the brother's child.

  • Surprisingly, instead of supporting the older brother, most of the family actually chose the cheater's side, claiming they should support him and his future child. 

    This led the 17-year-old to move out of his parents' home and move in with his grandparents, the only people who supported him through this dispute.

    "AITA for moving out at 17 when I was helping provide for my family because my brother got my (ex) girlfriend pregnant and my parents are supporting them?"

    I'm 17 and my brother is 16. My now ex is 16 too. I'd started dating her 2 years ago. And when she told me she was pregnant I knew the kid wasn't mine because we

    ForeignLynx3853 NTA I think your brother was well aware that you have been helping financially the whole time. But he decided to bite the hand that fed him.

    Tell your parents to send him to work. He's old enough, you proved it. If he can not only f your ex but impregnate her he can go to work.

    And shame on your parents! They could have taken your side, even while helping the two dum.' 5. But they never intended to take your side, you have been the cash cow, not a valued part of the family.
