Incredibly depressed

We tried and tried and finally got pregnant with twins. I was so happy at first. My boyfriend was too.

He started a new job working nights and now I find that he's sleeping during any time that he could be spending with me.

I'm wondering if it wasn't such a great idea. I will love these babies no matter what but I feel like the man I thought I was going to marry, doesn't care much about me anymore. I don't know what to do.
