Mentioning a Person's Name

The brain is attached to the mouth. We all have times that we've accidentially said something because we were thinking about it a lot. The same thing happens to cheaters. If your partner is constantly thinking about someone, they are likely to talk about them too.

Of course it's normal if someone new is in your partner's life even in a NON-CHEATING way that your partner might talk about them. So don't necessarily jump to conclusions. But if other things are indicating there is a problem, the constantly talking about the person or mentioning his/her name might be yet another clue.
