Ladies, if you’re in the dating scene, it isn’t just about knowing what to look for in a mate. It’s also about knowing what to stay away from. So we turned to CNN dating columnist, Audrey Irvine, to find out the top three guys that are total dating deal-breakers.

• First deal-breaker is the one-upper. This is the guy who always has to top everything you’ve done or every story you tell. If you ran a half marathon, he just finished his third triathlon. If you’re working on your master’s, he’s got a PhD. Irvine says a man like this can get exhausting. His experiences will always be bigger and better than yours. So before you consider seriously dating a one-upper, think about how you’ll feel when you’re celebrating a big work promotion, and he’s already figuring out how to top you!  
• Next dating deal-breaker is the back-in-the-day Guy. He’s the guy who’s always talking about the touchdown pass he threw in high-school, or reliving moments from his frat-house days. Irvine says there’s nostalgia, and then there’s “get over it already.” So if those memories are ten years old or older, he’s a dealbreaker!
• The final dating deal-breaker: The perfect-in-public Guy. The PIP is great when you’re out to dinner with friends, or at the company Christmas party, but he never turns it off. He always has to be the funniest, loudest person in the room, even when it’s just the two of you watching TV. The PIP is masking some deep insecurities, which is why he spends so much time hiding behind his larger-than-life personality. Unless you’re a therapist with some time on your hands leave the PIP for the next girl!
