Could you please go to the extended chart selection in Astro.com and make a synastry chart for the two of you? I've been out of the game so long that I can't do this in my head anymore.
I will say, though, after having read the other posts, that I think doing synastry will simply expose a scoundrel. Going by what you've said, he's a player, and has no intention of changing. Just exactly what do you want from him? Because odds are you're not going to get it. I'd say it's high time you took back the time and energy you're wasting on him and spend it on yourself again. He's not worth it and you are. How much kicking around will it take to convince you?
