Husband said he hates his life...

I don't want my husband to be bashed. I love him. I know he loves me. But I'm really hurt. We're expecting our first in December. I'm 30 weeks Sunday. I haven't worked in years, things were fine. My husband is going back to school this fall, next week actually. And hoping he can work part time at his current job but he isn't sure. He never really wanted a baby when we were ttc, I did. I thought over time and knowing it was a boy he might come around more and sometimes he does. But I still feel I'm in this alone. I feel im carrying a baby only I love, only I look forward too. I know he's stressed. We didn't think he'd be going to school, and it's going to be hard but it's temporary but I told him I'm sorry he hates his life, and he just told me it's fine, I guess it's what usually happens. It really hurt, I feel like I've ruined his entire life. I always wanted to be a stay at home wife and mother and I guess I got what I want with a man who isn't happy about it. I try so hard to be the best I can be, I know that doesn't make up financially but it hurts to be the only one excited. He's coming no matter what, and at times I'm afraid this will ruin us. I'm praying and hoping when he's here my husband will have a change of heart, maybe the truth of 'a man becomes a father when he holds his baby' but it's scary to rely on our future on that happening. I've been really emotional regarding this, I love him and I love our son. I feel like a horrible person. Like I've ruined his entire life the minute I became a part of it. I just don't know what to do, I feel I've pushed him to do all these things he never wanted and now it's finally catching up...
