He agrees for date night and ends up cancelling the plan because of his so-called other commitments. This is a classic excuse that is indicative of his dwindling interest in the relationship.
Every time you question him for not being responsive on texts, he plays the blame-game . He ultimately labels you to be super clingy or over-suspicious for no reason or rhyme.
Whenever you happen to pick up or check his phone even to check time, he totally flips out and tries to snatch it away from you. And makes lame excuses for doing so.
As a couple, you guys are fighting a lot more than usual, thereby giving him a good opportunity to be mad at you and storm out of the house and meet his lover.
He makes it a point to criticise different things about you that he initially found attractive and appealing. And also does not shy away from making hurtful statements.
He gets himself in a lot of trouble in grooming himself by hitting the gym at the late hour. And also treats himself to those extra showers to get rid of the scent of another woman.
Suddenly you will find yourself being showered with presents and jewellery. This is the exhibition of the classic cheater's guilt, because he can't help himself in any other way but be nice after what he has done.
You will often find him hopelessely daydreaming and not being there for you. Despite being physically present, his lack of interest in what you're saying makes it so obvious.
Don't forget to look at the usual cheating signs such as the distasteful lipstick stain on his shirt. If it happens once or more than once, its time you confront him about the same.
Strapping a lie detector to your boyfriend is not possible, so do look out for these cheating signs.
