I was in a relationship with a Sag for 3 years, it has also been 2 years since we broke up... your story sounds very similar to mine.
He told me he had to block me from all social media and we could never speak again. I think it is just a way of healing and to be honest I think it's a very sensible way of doing it. Part of me wants to reach out and try to talk to him but I don't think it's a good idea... He could still be hurting, or he could just be over the whole thing... either way it's probably for the best that I don't try to contact him. I think you should do that same, move on.
