Moving on after a heartbreak blues

So, recently, the guy I was with decided to call it quits because he felt overwhelmed by the relationship. The truth is, I had a few basic expectations that weren't met at first... and in my frustration and sadness, I said some pretty harsh things without meaning to. He never snapped back though-his silence hurt me more. Every time we tried to talk abotu it, h'ed tell me to drop it or find someone else if I wasn't happy. It's like the fights would just hapepn out of nowhere, but they were always painful.

There were moments when everything seemed great and I thought all was well...but then reality would hit hard. After our last fight, which clearly was my fault this time, he finally decided it was over. I'm pretty introverted, so getting close to someone means I get super attached-and losing that person really takes a toll on me.

If anyone has any advice on how to move past this and keep things heathier next time around, I'd be super grateful
