You have to be straight forward, honest, and polite.
tell them you are not interested. if you are friends with them, then tell them that you only see them as a friend.
Just about like that. Just tell him you know he is interested in you, but you are not interested. Thanks, but no thanks.
If a guy is interested, he will want to spend time with you, will call you, and will not make you wonder.
Well if you don't like him tell him you're not interested in him, and if you are interested in him tell him you like him back, or you can just ignore him.
You can tell a guy is interested in you if actually says he likes you or wants to go out
ask him.... scary but simple
You tell him politely that you are not interested.
Just tell him exactly that. Say 'sorry, but I'm just not interested in you that way', or something along those lines.
Tell her you are interested in her. If you want to show it and build a real relationship though you should seek to spend time with her. Talk to her. Be a good guy for her.
he keeps ignoring you and couldn't be bothered what happens to you.
I met a guy at a dating website called seekwealthy.com, he told me he is interested in me and wants to have a good relationships when we have chatted for about a month. I think he may directly tell you if he is interested.
The best way to get a guy interested in you is to always be yourself around him.
