Should I stop trying to be friends with this girl?
I met this girl online and we went on one date, no touching just a hug and no kissing but we both realized we love going to the gym so for the following 15 or so days we were just at the gym killing it. Then suddenly after 15 days she jumps me and starts kissing me and almost begging to try having a relationship together. I said yes for no logical reason, and 3 days later was at her house with the intent being sex, but I ended up leaving without doing anything more than kissing once she started talking about having kids in her future. The quickest way to kill my attraction to you is to talk about kids, and I knew there was no future for us.
So we decided we aren't meant for a relationship and went back to killing it at the gym, but it doesn't seem to be the same and she seems annoyed that I am texting another girl when we workout. Should I just give up on trying to workout with this chick or is it possible for her to just accept us as friends? She is the best workout partner I've ever had, and she has lost 16lbs since we started working out together I really like her as a friend and want to see her achieve the body of her dreams and find the man of her dreams.
Am I just hurting this poor girl trying to be her friend? Trying to decide if I should cut her off but I would feel terrible she is super nice and I only want what is best for her.
