Husband won't be there for first child

Jena
Okay so I'm not due for quite some time (August), but my husband told me the other day he won't be able to be there when the baby comes because he has a big business trip in August. I could never ask him to come back or not go because if he doesn't stay he would miss some huge opportunities for our growing family. I just feel like I don't have any other options at this point. It's our first child and I can't think of anyone else that I would want to be there or that could give me as much comfort as he does:/ has anybody else had to do it alone? Any advice that would make this whole process more comforting?
