Thank you all for the advice and resources!
My biggest hurdle now is how do I move on from this? We still haven’t spoken but I know this relationship is all but over. Even though I know he’s treated me poorly, how do I not miss the good times (there were so many, even though it might not sound like it!)? What if the “good guy” side was the REAL him and he just didn’t think I was “enough” to be that for all the time? What if he was just a jerk/drank because he was bored with me and wanted out but felt too bad to say it?
I realize this probably sounds irrational, but it’s where I’m at emotionally right now ...
