Please post pics of the GF so we can give you the best possible advice.
Grow a pair and tell her tuff luck your gettin some guns.
Will she divorce you? It not buy a gun.
He said "wife", not girlfriend.
Two entirely different species.................
Problem solved in 3 easy steps:
1. Go get your testicles from her jewelry box.
2. Tell her you're going to get a gun.
3. Procure gun.
Man up, because; a) she'll appreciate your assertiveness in the long run, unless she figures she married a eunuch and b) if she does get pissed off and leave - well, then you won't have to deal with that kind of person for the remainder of your life.
Win/win, really.
