How can I non-offensively reject a repeating invitation to "hang out" with romantic intentions?

I think being upfront with him is the best option. I think you’re misleading him by giving him excuses – so the best thing to do is to tell him that you don’t have those feelings for him but that you want to be friends.

“It’s very sweet of you to ask. I think you’re a great guy, but I don’t want to give you the impression that I’m interested in a date. If I think of anyone who’s a great match for you, I’ll send her your way.”

Have u ever seen White Chicks, if not see it and do what “she” did.

I agree honesty is best. But of course being honest can sometimes be hard I’m sure. You guys sound like good friends but obvious his feelings go deeper. Its only a matter of time before the truth comes free so tell him how u feel. Who knows after you tone down his persistence he may become somewhat more attractive. Good luck

“I’d love to hang out, because I like you as a friend, but I’m worried that I’ll send you the wrong message, because I’m not interested in a romantic relationship.”

Making excuses doesn’t help, especially if they’re believable, because he can delude himself—“oh, she really likes me, but she has to babysit her aunt’s pet rock,—if she didn’t, I’m sure we’d be having a great time together!”
