Bear with me on this.... I know you will say forget him but please let me know your instinct on this one.
Split up with ex five months ago. His decision. Said he couldn't see a future with me. I was heartbroken. Met someone else a few months later and it's going well with him but I do still think about my ex. Went to see what he's up to on Facebook. We are no longer friends but I wanted to look anyway. He has blocked me. I have not been contacting him or anything. In fact he contacted me before Christmas and I didn't reply. Why would be block me when I have not been hassling him? And why now after five months?
