Considering blocking my ex on all social media... Need some advice please?

[Stellz]

I’m 18 and just graduated high school. From grades 10-12 I was on and off with the same guy who used to be one of my best friends. Now that we are finished high school I still see him probably once a week or every two weeks. On New Years him and one of my friends made out at midnight. This has been a cycle for 4 years now and honestly I’m completely over it. I don’t want to see his pictures on Instagram, I don’t want to see his Facebook and I want him to know this is never happening again. I’m feeling like by blocking him on social media I can get my point across and if he needs to talk to me, this way he has to do it face to face (which I know he’s too scared to do lol). I know it sounds a little extreme but I was very upset by the situation and I really don’t want anything to do with him and I want him to know it too.
