My girl is bi and has had past girlfriends. She and I have been togethor 9 months now and a new girl she met (2 months they have known each other) went out to dinner with her. They have hung out lots before, but never done anything. They had several drinks and were drunk last night - ended up making out and touching each other in the bathroom of the resteraunt. I have known since day one that they were attracted to each other, and my girl has alluded to hooking up with her. I told her I dont feel comfortable with it. She said she wouldnt, though she joked about it. Now I am stuck with this aftermath and I dont know what to do. We live togethor which makes things really tough. I don't feel cheated on, though I should, but I feel like she has lost her accountability which is all a person really has when it comes down to it. She told me right away in a crying haste, she said she realized in a drunken state on the cab ride home what she did and we havent spoken since. I really dunno what to do.
