I've often experienced intense jealousy/envy since I was very small and though I've known for most of that time my feelings and internal responses are wrong I always seem to lapse and screw things up. I often see posts like these from the other side, saying things like "My bf/gf is extremely jealous/envious of me, what should I do?" to which responses are often "Run!" or something similar, but I would like to think that some, if not most, people like myself want to get better.
So does anyone else have any experience with this or insight that might be helpful? I'm 28, haven't had a relationship that's lasted longer than a year and a half, and have had dozens upon dozens that have lasted less than a month.
