A person can tell that a guy has feelings for you or that he loves you by the way he treats you. He should be affectionate and caring whenever possible.
just tell the guy your sorry and that you dont like him or her but say it nice and tell him that you're still his friend.
He'll pop a boner. You can tell, trust me.
it all depends on the guy
Tell him, "If I had feelings for him, I'd be his girlfriend.
If a guy truest you enough to tell you his feelings that means he really likes you.
tell him you want to have sex with him. and he might think differently.
tell him " i have more feelings for u then just as a friend "
"sorry, i like someone else" sincerely.
Tell him that your feelings have changed about him, and that you rushed into things without thinking
tell on him or not like him anymore
Not unless you tell him. Men dont read minds.
