I have a friendship that seems to be developing into more, he has severe depression and somehow I’ve taken it all on as my responsibility and I don’t know how to let go or if I even can. We message all day long and on the phone we sometimes talk for 4 hours. There are no healthy boundaries. I am absolutely exhausted by the responsibility I feel. He is suicidal and I’m afraid to detach because he doesn’t really have anyone else. It’s very much a toxic and codependent relationship and I just don’t see a way out. I love him but I feel completely burnt out and I think he has beccome very dependent on me. I am moving to a different city soon but even then I don’t know if I can detach because I’m so scared of leaving him alone, plus I have strong feelings for him. I’d really appreciate some advice.
