I could honestly write your posts. My partner admitted things too when he had a serious low point around xmas. He didnt move out of bed for 5 days and said there was nothing to get up for. Hes not as down and depressed now. But he is honestly like jekyll and hyde. You never know which one you will get. His mood and comments can sometimes be horrible and cold hearted. Then if I retaliate he doesnt like that then turns it round on me as if i have the problem. When i get upset about him staying in bed all day, he just says why have you got such a problem im not hurting anyone. Doesnt make it normal tho does it when hes got a family who wants to spend time with him.
Whats your partners mood like? He used to be such a kind and caring person.
