You have to be upfront and honest. Realize that he may be hurt - be empathetic and polite. It is not as easy as it sounds but if you don't beat around the bush - make it simple, don't allow it to drag out into a discussion - you have decided what you want and what you don't want and make that clear so there is no misunderstanding.
tell the girl to get over it. tell the guy that if it is over you are single.
When he stops talking to you/looking at you
Of course! There's no rule about telling a guy you like over the phone. Mac
you just simply tell him , don't sugar coat anything :)
Tell Him you like him too.
If he mentions that he's rubbing his dick.
Get over your shyness and just go up and tell him straight out. Surely you don't expect someone else to do this for you? If you really like this guy, then you are the only one who can tell him that.
Go to the guy and tell him to tell his girlfriend that he has a crush on you and that he thinks they should get over each other.
Because he cant get over his pride .
if the kiss is over 3 seconds long that means he is really into you
he loves you anyway
when your alone or somewhere private just tell him the truth and say why you want to stop the relationship. If you still like the guy and want to be friends then tell him that but if he reacts badly just give him some time to get over it and try acting more like friends again.
