<human>: I weren't shy as a kid, but after an early puberty made me bullied by classmates and plenty of divorce issues, I became very scared of getting close to others.

That was before I met my ex - I met her at a dancing class, and I smalltalked like I always do, expecting her to be another shallow friend. But she took all the initiative and dated me and made us a couple.

It was amazing at first, knowing love for the first time - that was until she began crying, over things like me not responding to a text within 10 minutes, having other things to do when she wanted to see me, or just talking to girls other than her.

In other words, she was very jealous, but I felt guilty, that I caused her all this pain, and constantly apologized and eventually wanted us to start at the same highschool, so that I'd have more time for her.

Since that school consisted mostly of girls, I could barely talk to anyone except for her closest friends, and none of them were in the classes I went to. Soon it began to remind me a lot of the bullying when I was younger, although not a physical one.

During spring, first year, I had enough and left her on impulse. Obviously her friends took her side and ignored me, same as everyone else I had never talked to before.

I had trouble finishing highschool, and later when I've started studying engineering I've had to retake several years due to stress - even though I haven't seen her in a long time, it feels like in every person, male or female, she's looking out through their eyes, resenting me in my defeat.

Am I going insane? I've tried so long to forget about her, but she never goes away. Love isn't there anymore, just the shame of what I am, and all the things in life I can't experience. How can I ever find a healthy relationship after this..

Can you give me the gist of the text in a nutshell?
<bot>: When memories your ex partner lingers and you start feeling the same shame for everyone as you do for your ex, how do you "move on"?
