Be kind direct, and honest
“It was nice chatting with you, but I’m not interested in a relationship.”
“I’m flattered, but I’m not interested.”
“That’s cool that you’re into MMA, but I don’t think we have much in common.”
“It was nice talking to you but I just don’t think we’re compatible.”
“I enjoy talking to you whenever we run into each other here but I’d like to leave it at that.”
Don’t lie or give a fake number
“I don’t think my boyfriend would appreciate me giving out my number.”
“Sure, my number is 217-965-287….4.”
“I’m meeting a friend, like, right now and have to go.”
Don’t be mean or sarcastic
“Did you honestly think I’d be interested in you?”
“I’m way out of your league, buddy.”
“You’re nowhere near my type.”
