My boyfriend suffers with some pretty complex mental health issues and it’s starting to affect my own mental health. A few months ago he went out and blew a lot of money on drugs and slept with someone else and I told him if he saw a doctor and got help I’d try to work through it with him. He has seen a doctor but his issues haven’t improved and he’s distant and uninterested and I’m ready to leave but would hate for him to do anything harmful because of something I’ve done. Do I just leave?
