I completely agree with you, I think it just hurts because it felt so directly connected. Being present for the beginning of her dates with this other guy, including them having a drink at the work place we all share before going home together, just really feels devaluing. It's a restaurant and I was right behind the bar they were both sitting at. I have never had any problem with womens histories, up the the moment we meet, but the fact there was this overlap which resulted in me being directly rejected to instead go sleep with this other guy really hurts.

Obviously it was a case of them having prior plans or something and I can't expect that she'll just cancel on somebody because a new guy appears, but that doesn't make it sting any less.
