Help! My Husband is having a hard time adjusting.

+kat+

We just found out that we are pregnant and my husband is, shall we say, having a hard time adjusting. We have an amazing relationship, but he never wanted to have kids. He has a high stress job and is now super stressed over this. He is in shock mode and can hardly even talk about it with me. He says he wants me to be happy, but the other side of that sentence is implying that he is not. This is super awkward for us. (We haven't told anyone yet.) 

-What can I do to help him adjust to our new life?

-How long did it take some of you dads to be ok with it? 

Thanks!
