Yes, you should be worried that your boyfriend will cheat again, irrespective of how much he has verbalized is undying devotion to you.

This is especially true when he has a history of cheating in his relationships.

Let’s assume this is the first time he has cheated on you.

Notwithstanding, there is a strong probability that he has cheated on his previous partners several times.

Look back on his dating history to determine whether he has exhibited this behavior.

This require that you think back to conversations that he has had with you about his past girlfriends.

Did he mention infidelity?

Did he give excuses for those moments of infidelity?

You accepted those excuses because he convinced you that he was a changed man.

You accepted them because you liked him so much that you just wanted to give the relationship a chance.

He has done the unthinkable and cheated on you too.

Discover his history by talking to his exes or his friends and family.

Building a good rapport with his friends and family, gives you an opening to getting them to be honest with you about his past.

This is how you gauge how likely your boyfriend will cheat on you again.

His dating history is absolutely key.

History repeats itself.

Be ready and accepting of whatever you discover.

A past full of repeated acts of cheating calls for you to take it seriously and not make excuses for him.

This is what people do when they are in love with their partner.

They find ways to excuse their partner’s behavior and lie to themselves by saying that their partner won’t do that to them.

You can’t be this person.

You have to take what you discover and use that to determine where you go from here.

A guy with a history of cheating has a stronger likelihood to cheat on you again.

Human beings are creatures of habit.

They tend to repeat themselves.

Another very effective way to figure out the likelihood of him cheating on you again is in the manner in which you discovered that he cheated on you.

In a context where he didn’t come to you and tell you face to face about what he did but you were the one who found out instead by your own means, there is a much stronger likelihood he will cheat on you again.

This is because you were the one that found out.

In essence, he was caught.

A thief is rarely remorseful until they are caught.

If he was the one who came to you to tell you about it and apologize about it, there is a higher probability he won’t cheat again.

He came to you on his own accord.

You didn’t catch him in the act.

This shows a degree of sincerity on his part.

This is especially true when he gives you a full account of what happened and doesn’t try to hide anything.

He gets detailed.

He describes what led up to it, how he was feeling at the time and what exactly was done during the act.

This is him being honest and disclosing everything that happened.

There are no guarantees that he will not cheat again, but your chances are better when he comes to you about it than when you find out about it on your own.
