Me (27M) and my partner (27F) have been poly for quite some time now. We didn't start of as open as we are now (admittedly for insecure reasons, that led to toxic boundaries) but have tried to grow pass those to have a stronger, healthier poly relationship. In the beginning it started off with only hooking up with the same sex. This wasn't the easiest decision for me at the time, because I don't have nearly as much attraction to the same sex as she does, but I wanted her to be happy, while also exploring other parts of myself. Soon after, she wanted to pursue actual relationships with people, of course with the same rule as before. This became even harder for me, since I already found it difficult to find someone of the same sex that I was attracted to, let alone wanted to be with. But I still wanted her to be happy so I allowed it. Eventually she found other partners, while I have not experienced much since the beginning of it all. After a while of seeing her happy in other relationships, I've come to terms with the fact that I just can't see myself truly being happy with the dynamic that we have, and that I would be more willing to open up our relationship to people of the opposite sex. (before I explain her response, I will say that she has offered this to me before because of someone from our past that I wasn't quite comfortable with being around again) she did not want to accept opening things up more, saying that she's gotten so used to the boundaries that we have, that it's difficult accepting me wanting to be with other people like that. I, unfortunately, compromised again to searching for a partner for the both of us, which suffice to say, hasn't been the most successful. I recently have been too disappointed by the results to want to continue trying, and believe that the only real solution is to try to completely open things like I originally wanted. I don't believe the conversation will go well, and fear it will be the end of our relationship. I don't want to be without her, but I also don't think I can be happy with the way things are. Seeing her in full, happy relationships knowing that I cannot have the same because of our rules is not something I think I can handle for much longer. What should i do?
