What if I don't love him anymore?

My husband and I have been together for 8 yrs, married for 4.  We have a 2 1/2 yr old and are expecting our second in about a month.  We had the weekend to ourselves to reconnect but I feel like it just drove us further apart.  We have nothing to talk about.  All he talks about is his job and I hate it. He doesn't care about what me and the baby did for the day and he's always on his phone.  I don't work, as I am a SAHM. If I was working and could afford to leave I think I would. I feel so stuck  I constantly am crying when I'm alone because I'm so frustrated.  He is so stubborn and everything has to be his way, no conversation about it.  Help please.  I'm so lost.
