How do you get when splitting up?

I get that we can all get a little crazy, that's only natural, stress, anger, grief, you name it, but as for me I see a pattern of those I gave up on that they got 50% angry, wanting to take charge, control, maybe thinking this was just another fight or I would change my mind, getting manipulative too, the other 50% was wanting me to give it more time. Me getting continuesly mixed messages. All but one was like that (ok they're not that many). The one who stands out to me was a guy I saw some girls look at, treat as if he was pure meat, I don't remember how we began dating but our relationship began with that we connected through talking, he was interesting to talk to, we could talk about anything or so I thought. The fear, insecurity I began having was how some girls treated him, treated me, and I had this thought he is going to be just like my dad, he's going to cheat. I began to get panic. All my prejudice, all my insecurity hit me like a wave. I would like to blame my youth because I did not read my own signs better, but that is too pathetic. I did not know myself enough. I did not know that me withdrawing, and getting panic like that meant I had trouble with trust and jealousy. He was asking me why but I could not tell him why because I was so limited by myself at the time. I could not be anything else than what I was in that exact moment. Guess it was one of those lessons I needed to learn to improve myself, but I'm sorry he too was to pay the price for it.

I have seen the same pattern when there were breakups when the guys would focus on things I could not care less for, for instance buying gifts I didn't want and felt frustraded, sorry for them at the same time. They knew the very reason or reasons why I, we called it off (except for the great looking guy who I did wrong), but they still focused on everything else. My partner did it too, when I left in a haste, panic. He would bring up things we before had agreed upon as now he would change this.
