It really depends on the situation and on the relationship the YOU and YOUR GIRL have. every one's relationship is different. there should always be trust. but there will be times when we all get jealous of each other thats when u really need to think wether its worth spending anymore time and effort on the relationship. if YOU feel comfortable with her going then it really doesnt matter what anyone else says. BUT if u dont feel comfortable with her going out with her freinds and you agree to it just because 30 people on IA said that they would, then ur gonna be at work beating yourself about it. go on what ur gut feeling tells u if u dont want her to go then tell her like an ADULT that u dont feel comfortable with her going. I personally trust enough in my wife and my relationship that i dont mind her going out with her freinds even though WE prefer to go out together.
