Pretty much the title but I'll give some backstory.
I (23F) have been on a few dates with this guy (25M) after he cold called me for a date. Right off the bat I wasn't physically attracted to him but said yes because maybe other aspects will be good. I wanted to get to know him a bit before a verdict so I went on 3 dates but I've ultimately decided that he's just not it for me. I want to cut things off before I string him along too far but I'm unsure of the best way to let him down easy without making the worst of things because it's likely I'll run into him again.
What have you said to others or others have said to you that worked?
