I dated my ex boyfriend for 3.5 years. In October, i was feeling bored and hastily made the decision to break up with him. Almost immediately I started dating someone else else, which I know it was cruel of me. I have broken up with my rebound guy and it has been about six months since the original breakup. In February I sent him a letter saying i still loved him and felt empty without him In my life. He responded by saying he loved our relationship but it was over. Then about a month later he blocked me on Facebook out of nowhere. He has texted me a few times with nothing to say. I miss him still terribly and feel like a horrible person for breaking his heart in the first place. Is there any chance of us being together? Why would he be texting me if he's blocked me on all social media?
