Kiss him
ignore him, and leave him.
slap or punch him and tell him buzz off or you are going to call the cops
If you have not seen the guy, then be very alert, lay suspicion on every weird guy and keep away from them.
who do that even he likes u but he does not saying it or he just want to show off to his friends that he has someone to harassing.. if it was the first option what u should do is to say some serous speech to him and if he keeps doing it that means the second option which means to try to finish everything he can get in touch with u at .
Make him have hardcore sex with you(suck dick etc) and then tell him i gave u a favour give me one
Manipulative observations
a sign of someone liking you is that there always teasing you, just so they can send more time with you. There really just into you if you dont like him ignore him and he wont bother after a while.
If the situation is bad, tell the cops. They can help you with anything from harassment to violence. If it's not that bad, tell him to stop and if he doesn't, say you'll call the cops.
You develop a thicker skin and try to suck it up and deal with it or you just simply ignore them
Avoid him and stay away from him since he can put you in trouble.
Get rid of him. Manipulation and Lies go together and are not healthy or good for a true relationship.
