What was the biggest mistake you made in your first relationship?

I was a little too controlling and tried to force him to be ready for things that he just wasn't. I realized after we broke up that we were still so young and he just wasn't ready for the things I was pushing on him (and understandably so). I was also too jealous and untrusting, I should have let him do his own thing more often instead of trying to constantly keep tabs on him.

my biggest mistake with my past relationship...is to expect so mcuh from him. and only take take take never also give give give ... after the break up i realized that when you really are in a relationship you have to have give and take and be responsible enough for attention.

The biggest mistake that I made in my first relationship would have to be I was waay to clingy and I saw no flaw in my partner. I seriously saw him as perfect and followed him around everywhere. I think he finally had enough of it. I learned pretty quick after that how blind and ridiculous I was but I'm glad I figured it out because he was definitely not the best guy I should have been with.

I chose the wrong guy to have a relationship with.
