My best friend and I fell out in January. He had told me the previous week that a night out might be happening with our other friends and that he would let me know. The day before the potential night out, I texted him to ask if it was happening and he said yes, that him and named other friends who were going. When I asked if I was invited, all he replied with was no. Upon further questioning he made a few excuses, he said some unkind things about my personality and we went to and fro with messages and then he blocked me!
We have since crossed paths on our commute around six times but he has always looked away very quickly or pretended not to see me, until recently when I was sat in an eatery, he walked past, saw I was in there and came in and we talked for a good ten minutes. I then messaged him on a social media platform that I am not on and said it was nice to see him and that I hoped he had a good evening. I didn't receive a reply. He sees the message though.
I think for him having seen me, made the effort to come and talk to me and then not message me back is really odd! Why would he do that? Any ideas into the working of his brain?
