After spinning plates and enjoying myself for a bit, I found a girl I thought I can LTR with. Been with her for about 5 months, told her early on my conditions for being committed: no drugs, no clubbing, no partying, respect our relationship. She agreed and hasn't done anything since. Her n count is 2 including me. She wants to get married later down the line, and asked for a promise ring (pre engagement ring) for Christmas. I am on the fence, due to couple factors:

1. She has guy friends she still says I love you to and was emotional intimate to before meeting me. Said she hasn't done anything sexual or romantic with any currently in her life. She doesn't see the problem with saying I love you to other guys than me while wanting to be more committed.

2. Is a part of a social club at school that introduced her to clubbing, black out drinking, partying, ecstasy and molly. She still considers them to be a very important part of her life. Her guy friends are from this club. Since meeting me, they try to exclude me from events, but she chooses to rather spend time with me instead. Biggest point of contention.

3. Is very physically affectionate to her guy friends. I told her to work on it or I will plate her. She said she is trying, but I see very little change so far.

Everything is good, except recently she seems to want to spend time with the social club again. Sometimes she says I can't go, because they're "exclusive" events. One time she went out for dinner, and on snapchat I see her getting drunk, doing shots with guys, and leaning on their arms, having a good time I guess. I don't like their influence over her, and her "family" is nothing kids who do nothing but drink, party, and do drugs. I don't want to commit to a girl who I can't see in her actions 110% loyalty and fidelity. What do I do TRP?
