Delete and block him completely off Facebook or any other social media... and don't think about him at all... don't see any photos not videos...
What did he do to hurt you by the way
Most Helpful Girl
Just remind yourself of the fact that he hurt you. I think a lot of the pain comes from imagining what could have been or missing how good it was before; but try to remember the relationship for what it was. Focus on yourself and move on. There are better things coming for you :)
