Is it ok for my girlfriend to go out late with her guy friends when I am on travel for work? Am I untrusting?

No!

But if you believe that they are just friends, then confront her. Ask her why she's out so late, and tell her that "that makes you worried."

Don't be harsh when asking, b/c it might ruin your relationship.

Communication is very important.

Honestly you cant control her, which is hwat sucks but mostly they just say guy friendz but then shell get drunk or sumtin and accidently do stuff with sum1.,. if i was u i would brake up wit her kuz doin that is kina like dating other guys... not a big difference

If you can't trust her, has she given you a reason not to? If she hasn't-- try to be trusting. If you get a strong bad vibe, then its you should be able to talk to her about your concerns. If she gives you a lot of attitude and guilt, I would walk away.

Do you trust her or don't you? If you do, then drop it. If you don't, the relationship is over and all that's left is the break up. So look inside your heart and find the answer you need. Good luck.

no, she sounds like a whore
