Please help me!Or give me your advice! I need it!

You dont HAVE to take this advice, but it may help cuz this is what I would do because I was sorta in the same situation, you see.
So first of all you can always keep him as a good friend and petsa the guy you wanna date, cuz I have many guyfriends and they all seem to accept eachother. And one tip of advice, based on past experience: Dont petsa a guy if:
You're not comfortable around him, If he smells like onions, If he is not hot, if he tries to seclude you from others, if he fondles too much and if he likes to be in physical contact... trust me... just dont.
Hope I helped... Silvershady

tell him the truth..that u like another guy and can't go out with him... but u can be close mga kaibigan though..if he really likes u then he'll understand

my friend had this problem before.i dont think this is right but my friend liked the idea.a guy asked her out and she sinabi she was going out with someone else.thats her payo not mine.

mine is tell him the truth.tell him you want to stay friends.

Go out with him if has got a nice butt.
If not reject him.
