A guy that has had a history of cheating in his past relationships, has a greater propensity to cheat on you.

Ergo, his history is a telling factor.

This is especially true if he has been continually forgiven in the past.

If his past girlfriends constantly took him back even after knowing that he had cheated on them, this has emboldened him.

He wasn’t getting any lasting punishment for his actions.

A few of these past girlfriends reprimanded at first.

Some went as far as breaking up with him.

Notwithstanding, several came back.

They forgave him.

A pattern of this in his past relationships, leaves him with the impression that cheating is an act that women are going to forgive him for.

This doesn’t do you any favors.

Keep a close eye on how much and how often he flirts with other women.

A guy who is already in a relationship glances or briefly smiles at a girl that he finds attractive, but leaves it at that.

This is for lots of guys in relationships.

But not all.

A guy who extends eye contact and smiles, following this up with all out flirting, is likely to cheat on you.

He justifies the flirting with so many girls as harmless fun.

It isn’t.

All it takes is for the right girl to respond to him in the right way.

She is at a point in her life where she doesn’t care and wants to be with a guy for the fun of it.

He sees an opportunity to get intimate with a girl that he knows isn’t looking for a commitment and the opportunity is too enticing to ignore.

He is that much more susceptible to giving in to the temptation to cheat with this girl because she is so attractive, so ready, and so clearly not looking for a commitment from him.

The chance to sleep with a girl who isn’t looking for commitment is too tempting to pass up.

He is used to flirting with girls that were or weren’t available.

This girl is making it that much easier for him to want to cheat with her, being that she is so forward and direct with what she wants.

He can get with her one time and let it be at that.

This is how he justifies cheating with this girl.

Consider how frequently he would much rather hang out with his friends than with you.

A healthy balance of being with friends and being with a mate in a relationship, is the right approach.

When this balance is too one-sided where he has a preference for being with friends, he cheats.

When he is so prone to going out with his friends and tends to cancel or avoid hanging out with you, he is putting himself in tempting arenas.

He gives in to peer pressure and decides to go for a girl he spots at a club or party, buoyed by a friend that tells him that she was looking at him.

Since your presence isn’t there physically, and he is surrounded by his encouraging friends, there is nothing discouraging him from making this move.

Throw the influence of alcohol into the mix, and he is more uninhibited to go talk to her and consequently cheat with her.
