How much should somebody be expected to contribute when they move into a partner's home?

One of the main practical benefits of living together when you're in a serious relationship is that you get to split the expensive cost of living. No longer do you have to worry about the invisible penalty of the singles tax; instead, you can budget while being (hopefully) safe in the knowledge that you have another income to act as a backup.

Still, this can't happen unless you and your partner are willing to have an open and honest conversation about finances. It is very easy to rush into the commitment of moving in without solidifying who expects to pay what, and sometimes some unfair assumptions can get made. Most people who have a job will expect to make some kind of financial contribution to the household, but the cost may wind up being greater than they thought it would be if they are not careful. Some individuals get into a relationship and get greedy regarding the other person's money. If this issue isn't ironed out early on, it can lead to a lot of resentment that makes cohabitation a chore rather than a privilege.

  • In an AITA post, a woman complained of the expectation to contribute financially when she moved into her boyfriend's house. When they first agreed to live together, he had told her that she would only be responsible for paying for groceries in the home, which he owned outright.

    However, once the moving-in date got closer, he decided that she should also be paying $400 a month for rent as well. She felt it was unfair of him to change the conditions at the last minute, but he worried about being taken advantage of. She wanted to know if she was wrong for not wanting to pay the rent.

  • Am I wrong for not wanting to pay rent + all the groceries to my bf who owns his house (no mortgage)?

    My boyfriend '45M' and I '33F' have been together for about a year and I moved in with him about a month ago. We have gotten stuck on this rent thing a few times and I need an outside perspective.

    He owns his own home outright, so there is no mortgage. It is a 2 bed, 2 bath house. One room is his office/hobby room, while I am a real estate agent, so if I need to work I do it in the living room/dining room, which is fine with me.

    Early on in the relationship, he said if I moved in, I would pay for all the groceries and that would be it. This is the deal he had with his ex, but they were together for 7 years. Then as it got closer to moving in, he changed his mind and said he wanted me to pay rent in addition to paying for all the groceries. Rent would be $400 + groceries for him and I. When I moved in rent was never mentioned and hasn't been for the last month until we got in a fight last night. On one hand, I get paying something, splitting all costs (utilities, property tax, ect), splitting or even me keeping paying for all the groceries. He feels like I would be taking advantage of him by not paying a rent, and I feel slightly taken advantage that what I would be paying would be covering all the groceries and that $400 would also cover all the utilities plus some. On one side I am saving money being here, so he should also be saving money, but what amount or split is fair?

    Other details-We do not live in a HCOL area and we both have EV's that we charge at home. We both clean. I do the vast majority of grocery shopping, cooking, and dishes. He mows and does all the yard work. We both own investment properties in the area and are building equity there.

  • been_blissed Oftentimes, men seek relationships with younger women because they seek to dominate their partner. How else is this pattern showing up? Is that really the dynamic that you want? Wouldn't an equal partnership be better? NTA

  • cfspd Is he going to ask for more in another month? Is he gonna request you put the Internet in your name in September? The issue isn't the cost, it's the switch up. If you decide to stay, whatever the agreement be, get a lease. He shouldn't just change his mind, so assure he can't.

  • usernamesarehard 1979 The house being paid for is none of your business. You're not an AH for wanting to split it different, but you guys should have figured that out first. Also, if he changed things on you, then that isn't acceptable without sufficient warning as well.

  • No-Expression-1106 Groceries are not fair at all because it's not a fixed cost + men usually eat more. Paying a fixed sum like 400 to cover your part of utilities + maintenance is fair. If you weren't living there he wouldn't be making extra money from the space and it doesn't

  • sound like he is willing to share. the space equally (like offering to share his hobby room) NTA and the fact he switched up after you moved in and brought it up during a fight as leverage is classless, childish and highly manipulative. So either he is a bad communicator or enjoys punishing his partner. Neither of which is sustainable in a healthy relationship.
