My husband of 10 years &amp; 2 kids decided the other day that he was all suddenly unhappy with me, and called it quits that we should never be together again. He seemed to be very happy and in love, so I can’t understand.. 

he went from making me feel like he wanted to always be with me because “ I’m me” to the complete opposite of making me feel like he wants nothing to do with me because “ I’m me”. I’m sure this is a manic episode because the way he’s acting is just so absurd and doesn’t seem like Him at all. I’m currently pregnant with our second baby and he wants nothing to do with her or to be in her life ( so he says) and the other day when I was at work he came to the house to gather all of his belongings including taking the mattress off my bed. Technically he paid for it a long time ago, but still. 

The things he’s doing are so careless and he seems so cold. It’s like he was so happy with me and to see me everyday; Our relationship was not toxic or argumentative and one day it’s like a switch flipped in him and he went from loving to come home and see his family everyday to the exact. 

He’s done this a few times and then came back home after a few months saying he wants to be with me more than anything and that he truly loves me and “ doesn’t know what’s wrong with him” - of course I take him back because we’re married and have kids together and all I want is my family, but I can’t have him keep switching every few years. 
 Just ranting because I’m so hurt and hope he gets out of this manic episode sometime soon.
