Late to this thread.
I didn't need FB to have this discussion because I have been there done that. And have family and friends who have been through it also. Some people's financial responsibility drastically changes when they move in with a person who has more or equal to offer.
First time it happened to me I made the mistake of not discussing splitting the bills. But I was very young and thought it would work out. I had a house and good job and she had a kid working part time. She moved in and got a full time job that was a decent wage. You'd think she would contribute accordingly. Nope.
Her logic..... I make more than her so I should cover all of the bills. She finally agreed to pay some bills but picked the smallest bills to pay; water and cable bills. Nothing was put towards rent.
It wasn't until I literally wrote it out on pen and paper the amount the bills had increased since her and her son moved in and how she was taking advantage of me. I showed her that she was able to keep 75% of her pay because she wasn't paying shit yet I hardly had 10% of mine left over. What made it bad was that her older sister was there and her own sister agreed, albeit reluctantly.
You'd think she would agree to contribute more. Nope. She decided to find her own place.
She moved into an apartment. Got evicted a few months later. Moved in with a female friend. Got kicked out a few months after that.
Point is that some people feel that when a person is doing better than them they don't have to contribute as much.
Right. Its about expenses.. It doesn't matter if you make way more if you're just gonna have hella expenses. She could work at 7-11 and have no expenses and still take home the same when it's all said and done
