My boyfriend of 4 years and I, we are not 'technically' together right now, but are still in a relationship of sorts. (We are working through issues of infidelity and trust that I caused.) During the span of a month that we did not talk to each other, he started talking to someone else. We have decided that we really do love each other and that we feel that we both belong together. He has continued to see the other girl and now wants a poly relationship, which is something he has always expressed a desire for. The other girl is still married but separated from her husband. They have issues of their own that I'm guessing aren't being dealt with. My boy friend and the other girl got together after bad splits. I kind of feel like they are rebounds for each other. He tells me he will never choose her over me because he loves me but doesn't want to let her go either because he likes her. Our goal is to get through things and live together again. I guess my question is, how would this ever work if him and I haven't completely worked through our issues and she's still married with her own relationship issues outside of this new relationship?
