Surprise pregnancy help

So I'm about 6 weeks, we weren't trying but we also weren't use any birth control methods and now he is not even remotely excited and is more than a bit frustrated, like its just my fault and he didn't have sex willingly ha! 
​ 
​This makes me mad because I have already had one miscarriage about 1 yr ago, do to trama and stress, which he HAD been  excited about that was unplanned ( I was on BC at that time). 
​Now I'm about six weeks, completely emotional, we are in the army and just movies to a new area so I don't have any friends. 
any advise?
