I was very close friends to someone for years. We were very very close at one time. I was basically his platonic shoulder to cry on, his sounding board etc. His marriage broke up and he then went on to have girlfriend after girlfriend. Our friendship remained the same, but contact wasn’t as frequent, but life gets in the way sometimes. He settled down with one, who was lovely and drove 200 miles to my hometown for the weekend with her. We met up for dinner as two couples, and everything was friendly. He then called off his engagement to her, and ghosted me out of his life the same time. Basically blocked me off Facebook, no contact, no reason why, nothing. 3 years later he requests to connect with me on LinkedIn (his job has nothing to do with mine anymore, so there is no career benefit from the connection. No mutual connections, he would have had to search for me.) I accepted thinking that he might message me to say hi whatever. Nothing. Absolutely nothing. He’s not even liked any of my posts. AIBU to think what’s the point of that? And just disconnect with him? AIBU to think that perhaps our friendship never meant as much to him as it did to me? And that he should just jog on?
