I turned a big age 10 days ago, my husband was awful to me on the day really unkind then apologised but made very little effort couldn’t even buy a cake, I told him on the evening how I was feeling and he dismissed my feelings, the weekend came and he was really apologetic said he wanted to make it right and fix it. I told him I was struggling to get passed his lack of effort and behaviour towards me, everything was fine, since then he’s been awful really short with me making little snide comments not spending any time with me making unkind comments, I’ve asked a few times why and he just said he’s fine he’s enjoying time on his own, However it’s got progressively worse and is effecting our 9 year old, I asked him again and he said he’s being horrible to me because ‘ he can’ I found that so awful, I asked him to leave our home. I just can’t have that it’s not fair, I feel terrible him leaving and I know he’s going to his moms and will lie about it but I can’t keep choosing to be treated like that. Have I done the wrong thing?
