If you have a sense that your guy is too good to be true, do not ignore it. Psychology professor Nancy Kalish, in an article for Match.com, describes the feeling you may experience: He is charming and very romantic, but you wonder if he has been this way with many other women. If you feel like he is playing a flirtatious game with you instead of actually trying to get to know you, he is likely not interested in a real romance.

Vanity is an unmistakable characteristic of a player or flirt, and if your guy seems more into himself than you, he is probably not the best candidate for a relationship. Colleen Crawford reports on the "Health Guidance" website that all womanizers are inherently vain, and it is their egos that allow them to believe that the way they treat women is acceptable. If he does not treat you the way you deserve but would never understand if you tried to talk to him about it, let him go and do not look back.

There is no more obvious way to tell that your guy is just a player than when he confuses you with other women. Carli Alexa Blau reports on "The Frisky" website that if he calls you by another woman's name, not only is there is someone else, but he cannot even remember which one you are. Crawford says a more subtle sign that he is confusing you with past lovers is if he constantly calls you pet names and never by your real name.

If he is overly quick to declare his undying love to you, take a step back. Kalish says that players use a "fast come-on" approach, by making grandiose statements of affection, as well as not being afraid of intimacy. However, Kalish states that normally men are more guarded with their emotions when they are genuine. If his feelings for you developed too quickly, they are likely superficial and he probably has hidden motives.
