He has appoligized for it, he does seem to show remorse. But at the same time he expects me to go from it being just him and I, to being okay lets all live together in a lifestyle I never thought of as a possiblity especially considering that the person he wants to have this with is my cousin.
I have made her move out because as of now we need to repair or try to repair our relationship (we have 3 kids together). I love him and totally understand his feelings and want things to work out between the two of us first.
The big issue is that 11 days after she left he made me decide to weather or not I could accept her the way he wanted me to. I told him that I didn't know and wasn't sure and because he was wanting a decision right then it had to be no.
