How to refuse someone when they say they love u?

what you could do is thank the girl for appreciating your existence...for loving you. but you need to be honest as well and tell her that she can't expect love in return coz you don't have any feelings to her. do it in a nice way and don't just avoid the girl without telling her what you really feel..definitely the girl will hurt but eventually she'll move on. just be honest and everything will be alright.

I would just avoid her entirely. Don't make eye contact, ignore her. If she says she still loves you tell her, "You don't know what love is! You don't love me, you're enchanted by me." If you don't want to talk to her, just go hit on some random girls whenever she tries to talk to you. She should take the hint.

You need to just be honest with her and tell her the truth. Be blunt, to the point, and do not leave room for her to think there will ever be a chance for her to be with you. If you allow her to believe there is a chance she will continue to pursue you. You can tell her that you are flattered that she thinks she loves you but you are in no way interested in her that way. It may hurt her feelings but it is better to be honest so that she will move on and not keep wasting time on someone who can not love her back. Best of luck to you.
