Is he nice 24/7? Come on. Just admit that it is unnatural for a sincere and honest person to feel ‘nice’ all the time. We experience different feelings and emotions. Fake guys know how to pretend and they usually behave in an unnatural way that feels dishonest.
Is he forceful or nice? Feel the difference between these two qualities. Fake guys often do something you never asked for to demonstrate how good and caring they are. There is a fine line between being a fake ‘nice’ guy and really a nice guy. So do not rush into conclusions with this tip. If the man is fake, then what he is doing to make you feel happy is actually a way to boost his own ego.
