I recently posted on a facebook page to find a partner to practice my favorite sport. Nothing romantic, I already have a boyfriend, I just want to practice my sport. Some guy (random stranger) agreed and we went practice the sport. He asked me if my boyfriend practiced the sport, I told him no, that he doesn't like it as much as me, which is why I was looking for someone.
So he knows I have a boyfriend. Then he started becoming awkward, asking me to go out etc... I declined and I think he understood but I still don't really want to continue to practice my sport with him.
But now I can't post on the facebook page (the only page for this sport in my city) because he will see it and I don't want to hurt his feelings.
How to tell my sports partner that I don't want to practice with him anymore without hurting his feelings?
