My girlfriend (6 months) keeps getting asked out by her single slutty friends to go clubbing and drinking. I don't like this - period. Her "friends" have one-night stands, sleep around, and drink frequently. How do I know this? She told me her best friend had a one-night stand with a guy; and I happened to snoop around her text messages with another friend claiming to have sex with multiple guys (after meeting them at a club).

I'm worried my girl may be influenced by them and will eventually succumb to peer pressure...or the temptation of cheating on me with another guy.

I told her upfront - "I don't want to control you. You can do whatever you want. However, the moment you cheat on me - realize that it's over and I won't be seeing you again."

She told me she won't be going to clubs or drinking without my approval. But is there any truth to this? Or is she likely to do this behind my back...without my knowing?

If we take the mentality PUA...then girls WANT to get fucked and are horny; there's no such thing as a "good" or real "loyal" girl.

Any advice on dealing with her friends and/or approaching this kind of situation from a confident standpoint?
