husband happy to leave?

Giulia
So my husband and I are splitting up.
I love him, but there are so many things..we can't really fix. It seems.
Do you think it's normal that he leaves the house (he went to his parents') and never even text me once about our daughter? She is 7 months tomorrow, and she is the sweetest thing ever.
How is it possible that some men just can't separate issues?
He is saying to his mom that I want a divorce, when it was together that we decided.
Now I'm going back and forth to it as I think of my daughter...whom he clearly doesn't think of these days.
How would you feel? I mean he doesn't even make an effort towards me, our marriage, our child!
