u wanna know the diference between you adn her? she isnt obsessed with you adn you are crazy about her. she prolly doesent think you care or she didnt. but dont let her know casue it will look bad. but you just need to get over it. a lot of girls arent willing to give up their social habits for a BF, and i probably wouldnt either.
just dont let it bother you but you do need to show that she is taken sometimes, cause this reminds me of one of my friends whos GF was alot liek that. the two of them adn a few others adn me would hang out sometimes adn she would just blow him off for the other guys . He just stood there watching and he would get so jealous. he didnt talk to other girls or anything. He would just stand there watching her have fun wit hother guys. he didnt show any possesion either so all the guys didnt give a sh1t about them. the relation ship ended in shame for him. he now mopes around fallowing her and , its just sad, yet quite funny.
dont be that guy!!!
and dont show jealousy either. you will lose all your power. and go hang with your friends. she does, you should too.
