Girlfriend going away for a little

Well ill start off with the story my girlfriend is originall from germany and moved over here to the us 2 years ago. Shes gonig back this summer for 3 weeks to live with a friend and meet her old ones. One thing im worried about is she is friends with a few guys over there that she says were good friends. Im worried now since were all older that she or they might do something sex wise. Me and her are sexually active and im worried she might do something over there with her guy friends she has since shes gone out with them before. Realisticly I would never even know if she did something with them if she goes. Question is should I say something , be worried, or am I just being ovvereacting and not even question it I would like someones opinion on it. This guy is basically second to me think since she keeps in touch with him every once in awhile. I have yet to even see him since he lives over there and stuff.

well my advice is just trust her because no relationship works without trust. plus you would probably be able to tell if she had done somthing with another guy by the way she acts when you next see her, if she's acting abit weird around you when she gets back then ask her what happend and go from there.

I wouldn't worry about it. Like domyb88 said.. TRUST is everything in a relationship. My boyfriend is from Mexico and we were dating and he went home for 3 MONTHS to see his family. It was the hardest thing ever. But, you just have to trust her! When she gets home don't assume she has done something.. she is going to act a little weird around you at first b/c she hasn't seen you in a while.. but if it keeps home.. question her..

shes not seeing family though and she openly tells me that he is the next best thing to me which is awkward but she also says she is unsure if she wants to go becuase she wants to spend her summer with me, so its both ways I cant really decide if I should be nervous or tell her anything before she leaves.
