Is it normal for someone after feeling rejected by you to suddenly hate you even if they loved you before?

sounds like he was ''curious'' about the whole thing,then probably started ''thinking'' about the whole mess and freaked out**''Im NOT gay,..Im NOT gay,..Im NOT gay,..)so then trys to ''flip-it'' like,.YOUR at fault for the whole entire charade,becouse YOUR gay,& tried to seduce him,.blah,blah,blah.I would stay away from him,simply becouse you-alls friendships been damaged by this behavior.
