Serious Question - Why does he hate me?

My N and I broke up in August. Though I'm certainly not flawless in the events that led up to this happening, I would really like someone to help me understand why this man hates me. If that means you have to be brutally honest about my own actions, I will accept your opinion.

First of all, I was with this man for 7 years. A long distance relationship that seemed to work well for him. I had every intent in moving closer to him however, due to the fact I have a teenage daughter and he wasn't the most accepting man when it came to children, I decided I would wait until she got a little older before I made this move. Again, it seemed fine with him and we actually spent more time together than most do living in the same city. He was the prince charming every girl looks for. Outside of being my first love, he was the only man I ever let me guard down with sexually. Though I could go on and on, I am 11 years younger, very attractive, driven in all areas of my life, wealthy, etc;.. Over the 7 years he some what trained me on the do's and don’ts.. I could never show signs of being needy, never ask to many questions (especially personal questions), never call to many times and in fact, let him be the one to pursue me. I would always need to play the game of 'I'm okay, without or without you'...

With all of this said, not only did I play the game, I convinced myself this is how I actually felt. In July I received a call from a friend who informed me he was seen all over some woman in a local bar. I was in complete shock! Actually I refused to believe it...

Given the fact I am four hours away, I higher a private investigator. I requested that she run check on his cell phone records, unknown email addresses, etc; I also wanted pictures if possible. (Heartache can make a person do strange things)! Nevertheless, I was not very smart in my selection process when choosing the PI. Not only did I higher some online nutcase from Mexico, after I paid her, she contacted my N and told him what I was trying to do. Later I did find out she went to jail for representing herself as a PI for other clients however, she truly burned me.

In short, come to find out, he was not only with the woman that one night in the bar, he's been playing me and her for two years! When I found this out, I went crazy on him, said a ton of ridiculous things, called him 20 times a day, etc;.. The woman moved 12 hours with her 2 small children (both under the ages of 5) to be closer to him. The ironic part to this, after months of getting my shit together and after this lady uprooted her entire life to be near him, I found out he ended the relationship..

So the question is, why does he hate me? I absolutely want nothing to do with him however, we have mutual friends and all of them tell me he talks terribly about me. Of course they only know his side of the story but come on, HATE is a strong emotion. Sure I invaded his privacy and though I would never lower myself to this level again, he is the one who was guilty! I was good to this man! I was planning on building our dream home on the coast sometime next year and only to find out he was living a double life.

He has removed me from every social network he belongs to however, I have noticed where he on occasion 'views' my profile. Why is this? Why does he hate me, bash me every chance he gets after 7 years of me being completely loyal and faithful. What gives? HELP
