just a slight problem

my girlfriend and i have been together 3 months, but we're in 'love', whatever that bizarre, abstract term means. last night, i left her house around 11:30, as she has to get up for an 8:00 class and i had to get up for work. around 12, she sends me a text message saying that she was invited out to a hookah bar with this guy, lets call him jorge, who she works with, and a group of his friends. jorge has expressed interest in dating her and sleeping with her, while we have been together. he has no regard for me. whenever ive met him, he wont look me in the eye.

gf told me if it made me uncomfortable then she wouldnt go, and i expressed that it would make me very uncomfortable as i do not trust jorge at all. she has gone out with work buddies before and ive been fine with that - even though she was jumped one time outside of a movie theater and beaten up, but thats another story.

i called her to talk to her about this, and she said she didn't want to not make friends because everyone associated her with being with her boyfriend all the time, i guess which is understandable, but her last boyfriend was a total dick that used to knock her around.

i told her that it was inevitable that i would end up needing someone more than they needed me, story of my life, that kind of thing, and that i was okay with her going out with people without me as long as it wasnt with jorge or his lackeys, as his lack of respect for me is abundant. we ended up squirling back and forth until she decided she wasnt going out.

but at the same time, i feel like a jerk. im just trying to protect her - and me, of course, and the 'unit' we have, but i still felt horrible, like i was holding her back.

that being said, i have no problem if people associate me with spending time with my gf constantly. i really do love her - once again, whatever that means - and she insists that she loves me and said that she wasn't going out because she knows it would hurt me.

did i do the right thing? i feel like a somewhat needy ponce, but she's not able to defend herself well, and if something were to have happened to her, i dont know how i would have handled it.
