Would it be ok if i sat out for the party?

long day ahead of me. It's my husbands birthday. And we're doing a military move starting today. I have lots of cleaning/errands to do and i'll help supervise the packers when they're here. Meanwhile I invited over his buddies to drink with him all day and keep him happy and busy. Then come the evening they're having a going away/birthday party. Well I won't know anyone there except his two buds. AND won't see these people ever again since i'm moving, AND they're all just going to be drinking and talking about the military all night. All I want to do is curl up to a movie in a room by myself and not be involved. If you were my husband would you be upset at all if I skipped out? It may also be relevent that i'm 6 months pregnant so i'm not exactly the life of the party lol.
