sad, heartbroken, disdapointedb

So I like this guy, but we had a fight because I got jealous, I ask if we could start again, fresh and he totally ignore me. I'm acting like if I don't care but I do care! What should I do? Men are so difficult 
My previous exboyfriend was possessive and abusive, I have never had someone truly love me. They say I'm beautiful, but I have become so col that I'm starting be careless around people, I don't love anyone.
