13. They aren't there for you

They’re suddenly not as present for you as they’ve typically been in the past, especially for activities you always used to share or during difficult moments.

14. They're acting cocky

One of the things that fuels infidelity is a sense of entitlement. A cheating partner can come to believe that they deserve to have an affair.


You can’t expect the cheating to stop if this sense of entitlement doesn’t start to disappear. If your cheating partner lacks an overall sense of humility, it might be a sign they haven’t outgrown this hurtful quality.

15. Things just feel off

Hopefully, you’ve processed your feelings of betrayal enough to make sure that your judgment is sound, but if something consistently seems off or unsatisfying about your cheating spouse’s behavior, then there might be a good reason that is the case.

Remember that every marriage is different

Obviously, you have to be careful with that last one because unfounded accusations can do tremendous damage to the recovery of your marriage, but you have a right to be concerned if these feelings come up with any regularity.


Remember that these are simply guidelines, not a set of hard and fast rules that apply in every single case. Don’t be alarmed if one or two of these signs pop up from time to time and don’t go looking for evidence where there isn’t any.

If we look for something hard enough, we’re probably going to find it whether it’s actually there or not, so do everyone a favor and stay as objective as possible.

Although suspicion and mistrust are perfectly normal reactions to infidelity, don’t drive yourself crazy with obsessive worry or nosiness. Using the signs we’ve listed as possible indicators, just listen to what your cheating partner is saying through their behavior and respond accordingly.

The signs of infidelity are there — if you know where to look.

You don’t have to give up on your marriage if your partner has been unfaithful. But you do have to be careful. Without becoming domineering or forever mistrustful, you have to pay attention to the signals that your cheating partner is sending and communicating to you.

People reveal who they are through their actions, but only as long as we’re listening to what they have to say.

It’s perfectly natural to be vigilant about your partner’s behavior after experiencing the pain of infidelity. It’s also a smart thing to do.


As long you can maintain a certain amount of vigilance without being hurtful or obsessive, paying attention to the signs your partner sends will be beneficial.
