What if a close guy friend asked me " What am I to You," What does he truly means?
If a close guy friend asks you what he is to you, then he is probably asking you if you have feelings for him. You should think about your answer before you tell him since it could alter your relationship for good.
just tell him that he is somebody important to you
Your probably the naive type and he tried to show you somehow that he likes you but when you didn't get it, he probably got mad and said that, most likely he likes you
