So im going to start this off with my fiance f30 and i m25 have been together two and a half years. This is really hard to put into words because i know it is my fault. I have opened and closed the relationship due to feeling guilty that they are non monogamous and my morals side more with strict monogamy. This last time of opening our relationship back up has been about 4 months and i am concerned about how to go about this conversation. They will not say anything to me honestly and truthfully. They will always say what I want to hear or avoid the question of “can we close our relationship” all together. Recently I figured out that they have a person that they have been talking to about all kinds of things that push 90% of our agreed on boundaries. They have been talking to this person for maybe a week and they tell this person everything that I have been begging to hear from them. I can’t trust them anymore. I have tried to edge the conversation and they avoid and get aggressive and then it into an argument with me. I don’t know how to go about this and im having doubts about longevity between us.
