I've known this man for four years we met randomly in a pub and we supported each other through lockdown. We used to meet up lots for drinks, dinner etc but both knew that we wouldn't have a relationship. I'm single with an autistic child who is very challenging and his messages and meet ups were a great outlet for me. He had gone quiet for a while and when we last spoke he talked about another women a lot and I suspected they were dating. He invited me to his birthday party last night and she was there and he confirmed they were seeing each other. Am I being silly to feel gutted that our friendship is likely over now with no more meet ups. Feel utterly depressed today.
