I’ve never posted on here but I think I desperately need some advice from people who may understand. My partner and I are in an open relationship. We are allowed to have sexual partners but not other romantic connections. I have been happily in open relationships in the past but my partner has never been in one. We are both in our late 20’s. I have tried to explain to my partner that boundaries/rules do exist in these types of relationships but he just does not seem to get it or care. I have expressed how uncomfortable it makes me feel that he does not tell the women he’s interested in that he is in a relationship. I find it completely unethical. I also don’t enjoy that he adds large amounts of women he speaks to at bars on social media that’s public that will comment on his posts. He even went as far as to hide the photos of us together on social media. I confronted him and he claimed it was because people he talked to thought he was cheating on someone. I tried to assert boundaries and insist he has to be open to compromise and he cannot lie to women he plans to sleep with and the reaction was not positive and turned into a big fight where I basically got completely tuned out and he almost broke up with me. He DID unhide our social media photos after this. This is NOTHING like my previous open relationships from the past. I love my partner very much but this all feels very toxic. Is there anything I can say to make him understand my point of view or is this situation too toxic/unhealthy to make work?
