<human>: Can you provide a brief overview of the text?

My High School boyfriend of five years broke up with me for many reasons(lies), mainly my best friend, stole said best friend(girl), and the rest of my High School companions with lies and one-sided story telling. I dropped off the face of the earth for over four years, trying to figure myself out and dealing with a broken family. A few months ago I got an E-mail from the woman he supposedly married about some things he had done. She wanted me to know that, if I had felt guilty about anything, it was not my fault, and he was merely an abusive ass. I also learned of two instances he had gotten away with while we dated where he'd cheated on me, and that he constantly,to this day, complains about me, in order to use me as an example of what a girlfriend/wife 'shouldn't be'. 

I sent him a note stating that I was not okay with what I'd heard, and that I was not to be used as guilt-fodder for any woman that he was with. It was a long-winded couple of paragraphs that basically stated that he humiliated me in the break up, and tore my life apart when I needed someone most(dad drinking, beating myself, my mom, and my sister), and reminded him that I did not even try to contact him, or anyone else out of respect. I expected the same. His reply was a letter wrought with sorrow and tales of joining the army because of his wife, the fall out of his adultery, and that he supposed I wanted him to die.

Against my better judgement, I gave him my Email and have been talking casually while he is overseas/offering my advice during his break up and other mental woes, and have recently been met with the information that he is still(somewhat succesfully) trying to date the girl who was my bestfriend, and other things about his personal life that I did not want to know, and thought he'd be savvy enough to realize is innapro, ultimately making me feel shitty over something I'd been forced to burry right after highschool due to how quickly I had to grow up because of my home life.
<bot>: Asshat of an ex re-connects and laments about his life and succesful relationship with long time lost best friend, probably in need of someone to feel bad for him.
