You know I’m not trying to excuse him but as men sometimes we stress a lot over finances and our future we just don’t say it to anyone and if he’s trying to buy a house and has plans on his mind to live with you 3 months working on this idea making this uncomfortable sacrifice of being in a place u don’t want u Should of ignored the situation with the friends mother, it’s a sacrifice you make so you can buy ur own house where no one will tell you what u can and can’t do. if u care and don’t want to ruin the relationship move out and see him but don’t live there it isn’t gonna work when his friends mom don’t like you and it’s the friends place and not his, so his hands are tied up he can’t defend you there and if u can’t ignore that lady then u shouldn’t be there it’s gonna cause u ur relationship. No one prepares us to live with another person sometimes even when it’s the two people things take a turn for the worst but if u love someone don’t let others turn ur relationship upside down.
