I wouldn't count on his changing anytime soon. Especially if he's pre-menopausal...lol (jk).

Really though, people typically don't change until they've run into the proverbial brick wall. I would ask myself: Do I want to be girl #123 (or whatever)? And don't tease yourself into believing that this time he will be different. If you want to go out with a guy who is what you are looking for, then wait until he stops being a player and acts like what you want for a while...but don't hold your breath.

I'm not in the guy-rescue business. People only change when THEY want to change (and after a lot of hard work), not when YOU want them to change. Here's an analogy--you don't marry a drunk and try to sober him up, you marry a guy who is sober (that doesnt mean that at one point he may not have been a drunk).

On the other hand, if you can go into this with no expectations and just want some fun (loosely speaking), then go for it.
