please, move on.
it's going to be the same cycle, over and over again, you get back together, he might return back to his old ways.
you two are going to be divorced. you both agreed on that.
you're with someone else now, you love someone else, you have to get that through your husband's head.
he can't just want you one second then hate you the next, and want you the next.... that's a disgrace to you and it is also very immature.
you have an apartment, a guy you love, a job, you're better of if you start off on your own.
get back together, he might revert to his old, drug-addled ways.
but then again, you wouldnt have to listen to me or any of the answers here.
follow your heart, and see where it leads you.
hope this helps!
