I dated a guy for 2 years. He was sleeping with me and someone else at the start of our relationship, he lied in general throughout our relationship and was generally being immature by going missing while out with friends and drinking too much. Ultimately I couldn’t trust him. We were friends for a long time before we dated and he did support me through my divorce, which was amazing of him! I ended thing’s because I couldn’t trust him and his drinking habits were awful. He was also rude to my son. I had to block him as he bombarded me with messages after we broke up and it was awful. I recently saw him on a dating app and he tried to match with me. I said he could follow me on insta and FB as it’s been 6 years since we split. I would like us to be friends, I even messaged him to say I would like us to clear the air as we were friends for a long time. He replied that he’s seeing someone serious and it’s not appropriate. I get that but it’s very odd that he’s asked to follow me, he watches all my stories within minutes, but I would like the opportunity to clear the air and thank him for his support and be friends. Am I being unreasonable? I feel I have tried to settle my conscience and I do want to be a good person and apologise to anyone I’ve wronged
