Is it okay to let my girlfriend go to her guy friends house alone?

Well, my girlfriend told me she is staying after school for stage props (like stage crew). When i was delivery chinese food, I saw her outside with her guy friend walking back to the school like after 4 hours school has ended. I confronted her about it and apparently she went to his house to catch a movie. She stayed there for 3 hours. Now i told her she can hang out with him, but i didnt expect her to go to his house because i thought they were just gonna stay at school. My question is, should I be upset or should I let it keep going? Just to let you know I dont like this guy because he cheated on his girlfriend.Is it okay to let my girlfriend go to her guy friends house alone?
I think you should let her go and when you do that tell her that u love her no matter what she does or whom she talks to. Then out of respect for belief that you have on her she will restrain from doing anything stupid that might hurt u because where doubt exists relations dont. Even if she goes she wont do anythin stupid because she knows that u trust and love her and infact she'll spread a good word about you. Or else she will keep telling that her bf is very possessive and keeps doubting her a lot.

good luck:)
Any opposite Sex relationship is always there for a potential f### plain and simple. Ask yourself this... How many of your Guy Friends just have a Girl that is a Friend that they don't want to F### ? Yeah, now you catching my drift ? Trust me that so called Guy Friend of hers is just waiting for you to screw up one Night and BAM ! You just lost your Girl to the (Guy Friend). No Man, is Friends with a Woman unless he wants to F### her. I'm 36 and I still see this, even in the workplace on a daily basis.Is it okay to let my girlfriend go to her guy friends house alone?
seems like it might be harmless, if she starts spending alot of time with him id be worried. ask her why she didnt tell you she was gonig there
I Personally would not allow my girlfriend to go to her guyfriends house alone, but things happen when that happens so if i were you i'd be pretty upset :(Is it okay to let my girlfriend go to her guy friends house alone?
She should be allowed to do what she wants, but just let her know that you don't like it and hopefully she can respect that.
