<human>: So my girlfriend and I have been together for 4 years and recently moved to a new city and we have been here for a few months and we are almost fully settled in. Both are working and we are starting to make friends. She made a friend from work who also just moved to the city a few months. I am happy she is making friends since it gives me some time apart a few weekends a month, but. Her new friend is kind of a sex addict. She's always meeting and trying to hook up with guys putting my girlfriend in an uncomfortable position when they go out. My girlfriend is the type of girl who is more of a follower (as bad as that sounds of me to say). I'm just worried my girlfriend will try to impress her new friend and put her in a position of something horrible to happen. Weather that is her getting a little to drunk and hooking up with a guy while her friend is in the other room doing the same thing, or my girlfriends friend leaving her in a bar in a city we barely now much about. How would I handle this? Should I voice my concerns or just shut my mouth? 

I'm not the type of guy who likes to go out drinking so I really don't know what it's like to be in the situation she could be in. I think I've only ever went out a handful of times and that was with my girlfriend. So I have no idea how to handle this.
