Green-Eyed, Jealous much? Options

[Listelle]

My boyfriend is the nicest guy ever, really. With that said, I can tell you that his two best friends are, and the majority of his social circle consist of, his ex-girlfriends (he was a bit of a whore in high school). If he's not with me, he's probably with one of them. Lately, it's been bothering me a bit. I know most of the girls and a one or two I consider close friends but still, I have moments of complete jealously that are, for the most part, unjustifiable. I've mentioned it a couple times to him in passing how I felt about two of the girls, but somehow it ended up as a joke we laughed over. The two girls I've mentioned made passes at him while knowing we were together. One even dared to go as far as to kiss him on the cheek on V-Day.

And it's not that I don't trust him or am really worried that the girls will try anything more. It's just with the school year coming up and me having to work now, there's less time to hang out with him. I'm afraid that I'm just going to grow even more jealous as time goes on and evetually ruin a really good relationship (20 months tomorrow!).

So.. Have you ever been jealous to the point of insanity in a relationship? How did you handle it? And how would you tell him how you feel without seeming controlling and neurotic? Advice and stories of your own would be lovely

Sorry for so long of a post. This is actually the short, watered down version of the situation. The more intense story lives here, with the password Tiger Lily if you're interested.
