You will find them staring into the mirror, hoping to impress their new prospect. They think they can attract and earn the appreciation of the opposite sex with their good appearance. Although everyone wants to look great, if your partner is obsessed with their appearance, it can be added to the other warning signs.

Loneliness is their greatest enemy, so they keep jumping from one relationship to another. They want to avoid facing their insecurity and the hurt caused by reckless behavior. If your partner mostly avoids being alone by flitting between relationships, it is a huge red flag.

21. They have cheated before

You must have heard the saying, “Once a cheater, always a cheater.” Research has shown that those who cheated before are three times more likely to cheat again (1). If your partner has cheated in the past, there is a chance that he or she might cheat again. They may swear that they are not deceivers, but see if their words translate into action. Do they feel guilty about what they do? Do they take responsibility for their actions? Is there any improvement in their behavior? If the answer to these questions is no, they will likely do it again.
