CAN ANYONE HELP ME TRY TO UNDERSTAND HOW THIS ASSHOLE THINKS? {MY EX}?

My ex boyfriend. and i went out for a year. he was the super jealous type. he wanted all my passwords and everything. we were crazy about eachother at some point and eventually he fell out of love. i went through all these healing phases and i still sort of like him but i'll be happy if he's happy. anywho he comes back to me here and there and i use to take him back which ended up us having sex. then after some time passed. he hits me up on aim and my current boyfriend was on my aim. so my current boyfriend tells him whos this and then my ex says he's my Bff. so my man tells my ex he's my man and my ex started flippin out saying things like ';i hit that for a year now'; and ';You hittin that'; and which boyfriend are you? and ';Oh im just tryna tell u how she is'; after that my boyfriend blocked him and deleted him from my buddy list. this really hurt me for my ex to say that kind of things especially to my man. WHY DO YOU THINK HE WOULD SAY THESE THINGS? if he was pissed why would he take it out on me that way. and recently he adds me on facebook and i accept his request so i wrote him a comment and it read ';Hows it going'; and he responds and everything we ask eachother hows everything and we both say ';everythings gd'; but when i check back later he deleted me on facebook That's another thing im wondering about. Why the heck would he delete me all of a sudden? and should i even hit him up and ask him. im just curious. and for some reason it bothered me a bit. HELP. EXPLAIN PLEASEE ? =/CAN ANYONE HELP ME TRY TO UNDERSTAND HOW THIS ASSHOLE THINKS? {MY EX}?
I like you as a person, but I don't like your ex. He is manipulative, and mean spirited. I think the person you revolve around has to have something besides their agenda to utilize. I like people who share and care about all we like and care about. Any body else is putting them self first and you and your friends last. Think about it. I am saying being true to yourself and those you love and want good things means putting yourself on a less priority plane than them. Can I sum this up better than that? I understand why you are bewildered by his selfishness. He only thinks about himself. I hope I showed more compassion than he could ponder and place in your mind. I would keep trying just to prove that point.........CAN ANYONE HELP ME TRY TO UNDERSTAND HOW THIS ASSHOLE THINKS? {MY EX}?
Move on! Change every password you gave the jerk. He's not your friend. It sounds to me like he only calls you up when he wants to get laid. He's not worth your time. Stop caring what he thinks. It will take time, but you will get fully over him. Seriously, though, read what you wrote. He's a jerk, right? So stop communicating with him!
