I dunno about you all, but if my girlfriend just went and broke up with me unexpectedly because of certain aspects, I'd feel bad and want her back. Perhaps if I said certain things that made her think those aren't the traits I still keep, or if I suggest a way to change those things to her, maybe she'll come back to me... (/sarcasm off)
If I recall from your original thread, it wasn't a good relationship, of course there were good times, but it's the bad times when you see people show themselves. Therapy does help I'm sure, but I'd just be weary.
Before you met this person, you had an idea of what kinda of relationship you wanted... Just keep that in mind, never compromise, never give up, never surrender! (In the ever poplular Galaxy Quest voice)
I hope you find your answers to whichever route you take
