threesomeHorror

So my gf and I decided to have a threesome with a good friend of hers (she has interest in Polyamory, and I must add he was very blessed you know). They haven't talked in a while and were always off and on when it came to convos. (He a cancer, she a scorpio)
I thought it would be fine until I walked out of the bathroom and saw that they had already been kissing. My gf ensured me that I would have something to turn me on a bit more walking on that. IT HAD THE COMPLETE OPPOSITE EFFECT. Instead of ending the night I figured that I would be fine and went along with it. I did not have sex with him but my gf did and she enjoyed it. I enjoyed the bit of control I had over the situation (telling him to do this like this, and that like that) but I still wasn't convinced that I wanted to have sex with him. When it was my turn I ended up just giving him head. The craziest things was the fact that she didn't even notice that I was rubbed the wrong way at all. After the situation, I confronted her and asked that she stop communicating with or hanging with him without me for the time being. Instead of going with what I asked, she denies that offer and claims that she will not stop talking to him for the mistake "we" made. That is wasn't his fault and she shouldn't have to stop talking to him, so she won't. I still feel like I would have been better off not coming out of the bathroom seeing them kiss but. Whatever. We finish and I trusted that she would discuss things with him since he doesn't deserve to be dropped. Weeks after she admits to finally confronting him about ending the boo, baby, love, hun talk. To end conversing after hours (but she still text him good morning before 7 most times). BUT HE STILL DOES EVERYTHING. Did I mention that after asking that she not see him alone, she asks him to pick her up from work so they could talk and smoke in person. The only thing they have in common is rapping. She says that his height and intelligence and communication skills are three of the things that he lacks and couldn't possibly have a relationship with him, let alone baby. But last week he randomly asked if she wanted a baby, because he would give it to her. WTF She then seems to have said I couldn't be that vain (going into height and so on) BLAH BLAH. He admits that he has never loved the child of his baby and has never fallen in love. I am very worried about his and her interaction. We have been together for a year almost now and I don't like hearing his name.
