<human>: This all happened last night.
This isn't the first time it's happened...

It's happened in every relationship I've been in. 

I'm not a bad looking guy, I don't consider myself clinically insane, I'm not clingy, I'm not vain. Why after a few months of every relationship do the women who have been in my life think they would be better getting back with an ex-boyfriend? EVERY. TIME.

It's begun to leave a bad representation of women in my mind..Something I know I don't want but it's so hard not to be bitter about it. 

I had my first girlfriend at 16, then 18, then another at 20, then this previous one at 23. I'm not one to go out to date a whole lot, but I'm at a 100% success rate of girls wanting their old ex. 

I don't know what I'm actually asking..More of a rant.. Something to get off my chest.. Sometimes we have to go fall apart so that we can be put back together. 

Feel free to ask any questions if I didn't give enough information

Can you give me the gist of the text in a nutshell?
<bot>: Every single relationship I've had from past to present has ended with them wanting their ex. What is wrong with me?
