Most Helpful Girl
You both need to come to an understanding that we're only human, we even look at other guys/girls doesn't mean we want them. You should trust her enough to hang out with guys that will respect that she's in a relationship if not, she should be the one to end her friendship with them and vice versa for you. You two aren't giving each other reasons to be jealous, it's normal for opposite sex to hang out and you both worry too much. At the end of the day you two are with each other for a reason, and who knows what the future holds, but presently you two are together xx

Listen. There is a fine lne between jealousy and controlling. You don't want to control her life. My girlfriend has guy friends and I have girl friends too.
It's about trust. You need to trust them and their feelings for you otherwise you'll become an overbearing person. She will then most likely dump you.
It's okay to be jealous and express it. I just did today. I don't expect her to tell me to stop being friends with some of my best friends, so i don't expect the same from her.
