he well for one, you might want to find out more about him, try to get to know him. If he likes to goof off alot most likely he will be a great catch!
tell him you're nice to everyone.
be nice to him and tell him i love you
a nice guy is nice to everyone and doesn't talk bad about anyone. a nice guy would open the door for her and tell her she looks pretty. but you can't just act like your nice you have to be nice and if you are she will notice.
That's a good thing! This depends on the kind of guy he is. If he is a player and/or has had many gf's, take the I Love You with a grain of salt. If he is a nice and sincere guy, then tell him you love him back!! but only tell him if you really mean it.
you can defanitly tell when the guy is always looking at you and if he is nice to u and sometimes if he teases you or picks on you
You just tell him
if a guy thinks your hot he will hang around you and tell you that he thinks you look nice or say you have nice hair
you tell them there a really nice guy but you dont really like them
Most of the time the girl doesn't realize he's a cheater until it's too late. Unfortunately for all the nice guys out there it's hard for a woman to tell the difference between a good guy and a player at the beginning of a relationship because the players are so good at pretending to be genuine. I think some of them are better at appearing genuine than the real good guys, which is why girls always fall for them.
Just subtly tell her "wow, you look nice today"
there really is no for sure way to tell, but if hes nice pays you compliments, and is really just a nice guy
act nice and smile.
