I Cant Change the Past But I Can Change My Future

So for the past 2 years I was so inlove with this guy (so I thought it was love) but he did so many messed up things to me and slowly we became more distant by day and on December he told me to just forget about him and to never look for him again yet he still has me on all social media😐... Ok so I started dating this other guy 1 month ago and now I'm getting all this messages and calls from him and his friends talking about he misses me and he wasn't thinking right and wants me back in his life 😡 NO!!! I call that bull**** now that he sees me happy he decided that he loved me well now its to late cause now I decided that I want to be happy and that will never happen if I'm with him✌
