Wow. Just read his texts.
two things come to me immediately. The first comment is so nasty "good luck finding somebody else". Wow. Does that sound like a man who feels lucky to have you? A man who values you?! No. It does not, and he wonders why you're bailing now.
I'd stop bothering to mention marriage now. Just focus on getting him to leave the rented home that is your great uncles.
You had your agenda, which was to be part of a team and to have security and to be loved. Your needs weren't being met, so you don't have to stay with him.
His texts make it clear that he doesn't value you but is still going to do his level best to make you feel obliged to stay with him, and to mock you for wanting security.
He doesn't get to hold on to ALL of the security, whilst mocking you for wanting a different type of relationship.
Chareen, I wouldn't even bother arguing about it anymore. He will never acknowledge that he has been unfair to you. Just keep saying ''you're not what I want, this isn't working for me, I can't afford you, I can't afford this life".
Just keep repeating the same drippinng tap statements. Do not get drawn in to any court case style trials. Where he makes you justify your decision to end the relationship over this issue.
To hell with his oint with the house.
