Okay. I've tried getting advice from my friends (like I normally do), but they seem to be stuck on "Dump her". I'm hoping I can get better advice here.

Stick with me, there is a lot of background, and I really want advice from people who know the whole situation

My girlfriend and I have been living together for a little over a year now. When we got together, both of us were polyamorous. I didn't really practice, since my last two girl friends were very much monogomous. She had a couple other boyfriends, and a couple that she had regular dates with. That was all fine by me. Sometimes you've got a lot of love going, sometimes you are lucky to have the one you've got.

I think it was around July that I started talking to a woman that I met online. There was a mutual attraction there, but my girlfriend gave the red light so it was never pursued. I always got the impression that she didn't believe that I was being faithful. She would make sure to be available whenever I made plans with this other woman (Yes, her and I are still friends but have never been intimate). She would hover over me when I was sending e-mails or IMing. I let it go, but I have serious problems with a lack of trust.

Things continued. She dropped one of her boyfriends, but was still seeing the other one and the couple. That tappered off after a while, and she started complaining that she didn't feel comfortable playing with others if I wasn't. I told her that I would start looking, but that I really felt more comfortable when it just happened.

Well, eventually it did happen. I went to a New Years party with some old friends of mine, and after a lot of drinks ended up sleeping with a friend I've had for years. It was a little awkward (Until then we had always referred to each other as brother and sister), but we realized it was something we wanted to do for years and had just been afraid. I told my girlfriend what had happened, and she flipped. She put the red light on that friend of mine, and basically asked that I don't have any other activities until she could come to terms with it.

So, last month she told me that she was fine with me sleeping with other people. I had no real intention of doing so after the last blow up, but I agreed just to keep things simple. The first person I talked to (Who I had no intention of sleeping with) was immediately vetoed, along with another jealous fit.

I told her flat out that I was not going to see any other people. It seemed like the right decision to make. She has been going on ever since about it, along with accusing me of cheating on her.

Now. I don't want to break up with her. Aside from this little thing, she is a really good person. I know that a lot of this is me screwing up. I should have seen the signs that she would not be okay with me sleeping with other women, and never put myself in that situation to begin with. What I need to know now is how to fix it. How do I convince her that I am not cheating on her, and that I care about her more than I care about being poly?

I can fill in more information, but I think I've rambled on too much already.

Okay you have done nothing wrong. Poly mean that you have more than one sexual partner right? I looked it up lol. Anyway if she is having people on the side then you should be able to. I would sit her down and tell her you want a monogmous relationship, because being poly is causing too many problems.

Much better advice then my friends have been giving... lol

While I don't really have a problem with closing the relationship, and I think my girl friend is assuming that is the only option if I don't have other partners, I don't want to take that away from her. It doesn't bother me when she sees other people, most of the time it is a big turn on. While I enjoy my time with others, it isn't going to kill me to give it up.

I understand why she is jealous, and my first attempts were to reassure her that no matter what I do with others she is still my primary. When that didn't work, I told her I wouldn't see other people, and I've stuck by that. The big problem is that she doesn't believe me. When I try to make plans with my friends, she goes out of her way to be there. It is killing her social life, and making her resent me.

I just want to get her to trust me. I'm really not the cheating type. If I say I'm not sleeping around, I mean it.
