Don't Want To Him To Get The Wrong Idea
There is this guy who likes me, but I don't like him back. He kind of puts moves on me like rubs my back, but at the same time he does it to everyone else. He knows I don't want a relationship right now, but I don't want to lead him on.
I don't know how to not lead him on or let him know I'm not interested in him without being a jerk. I was going to ask him to prom and go as friends, but I don't want him to get the wrong idea. I don't know what to do.
The best thing you can do is be straightforward and honest. Think about what you want to say before you say it, maybe even practice with your friend first. You want to be kind but honest. If he is a real friend then he will respect your wishes and understand. If he responds badly then you will know if he would be capable of respecting your desires. You could say something to the affect, "I care about you as a friend.
I don't want our friendship to end, in fact I was thinking about asking you to prom, as friends, but I didn't want to give you the wrong idea or lead you on. I think you're an awesome person but I only see you as a friend." If him being affectionate towards you makes you uncomfortable then you have every right to let it be known, of course it would be better if you did it nicely but if he doesn't stop then you might have to be more blunt about it.
You might want to first try using body language by moving away from him when he rubs your back. If he doesn't seem to get the hint that way, then you should say something about it.
Honesty and kindness are your best bet. Let us know how things turn out and we wish you all the best!
