There is more than enough information out there about how to catch a cheating partner. A simple Google search will yield more than 10 million results on how to catch your unfaithful partner red handed. You will find just as many websites, social media posts and blogs dedicated to recognizing when your partner has strayed. But what if you want to recognize the problem before your partner does cheat? Many betrayed partners can look back with the benefit of hindsight and identify that something was wrong in their relationship. If you can spot the clues beforehand, however, you might be able to save your relationship or at least save yourself the pain of being blindsided by your partner’s affair. Here are eight signs that your partner is going to cheat.

They Seem Bored

Some people need constant influxes of “newness” in their lives. If your partner is one of these people, boredom can be the root cause of an affair. Boredom in a relationship is not just limited to boredom in the bedroom either. In an established relationship, excitement and passion is often replaced by certainty and comfortable stability. For most people, this is an acceptable and even welcome change. Fiery passion is enjoyable, but most people come to prefer the certainty that their partner will be there for them and their partner’s solid support. Unfortunately, for some people, the death of passion equates to the death of the relationship. They want the constant high of “will-we, won’t-we” and the intoxicating giddiness of the honeymoon phase.

If your partner seems bored, take a hard look at the relationship. If both of you are living on autopilot, your partner’s boredom might be justified. In that case, a couple’s weekend away or a date night without the children might be all that is needed to reinvigorate the relationship. If there was no apparent reason for your partner to be bored in the first place, however, it may be time to start watching out for the other woman.

They Are Deeply Invested in a New “Friend”

New friends are wonderful, and most partners in healthy relationships encourage each other to get to know new people. Most people also find no issue with partners having slightly differing sets of friends. Mutual friends are important to a relationship, but a happy husband should not feel threatened when his wife wants to have a girl’s night. Similarly, a wife should not be concerned if her husband really wants to spend a Saturday afternoon with the boys.

Regardless of whether a person is single, dating, married or divorced, they are going to be invested in their friendships and will likely have close friends of the opposite sex. This, in and of itself, is not a problem. You might need to be concerned, however, if she never stops talking about her new “friend.” If he seems more invested in his new female friend than he does in you, it might be time to be concerned about this “friend” sucking the emotional energy out of your relationship.

They Are Distant

It is frustrating and concerning when you can tell something is wrong with your partner, but they keep insisting, unconvincingly, that they are “fine.” While every relationship has its occasional exchanges of “What’s wrong?” “Nothing,” and “Are you okay?” “I’m fine,” these should not be the norm.

Emotional distance is cited by cheaters as the main reason they stray. If your partner has been consistently distant recently, reach out to them, and try to reconnect with your partner. If you cannot seem to get through to them, you might need to start keeping an eye out for the mistress.

They Are Angry

It is rarely a good sign when your partner is always angry. That anger, however, could have any number of roots. There could be an obvious reason for the anger such as you crashing a brand new car when you ran a red light, or the reason could be more subtle. One of those hidden causes could be a lack of attention from you. It is not logical or rational, but human beings of all ages prefer negative attention over a lack of attention. If you have been constantly distracted by your children or working extraordinarily long hours at work, your partner might be looking to pick a fight simply to remind you that they exist.

Anger can also be born out of a feeling that their needs are not being met. These needs could be anything from a reasonable desire for time with you to the truly ludicrous. Regardless of what they are, a partner that feels their needs are not being met is likely to stray. If you absolutely cannot meet your partner’s apparent need for a weekly golf retreat, soon you might not be the only woman is his life.

They Are Apathetic

Everyone knows that one person who never seems to care about anything. You may enjoy spending time with them, but figuring out where they want to meet for lunch is like pulling teeth. Every request for input is answered with “I don’t care.” This is irksome in a friend but can be a sign of much deeper problems in a romantic relationship especially if the trait is new. You might not have anything to worry about if you have not been able to get a dinner recommendation out of him since your first date, but if he used to be Mr. Opinion and now he does not care what restaurant you go to, you may have a problem.
