How do you know the guy your talking is a player or not.

sounds like a might be a player :/

From what you've described of this guy, he sounds to me like a bit of a player, or at best someone who is not solely interested in you! He's happy to talk with you and flirt with you and say all the right things to keep you interested, but then he'll disappear and no doubt be saying all those things to other girls! I tend to think that if he was solely interested in you, he would be around a lot more and make you feel more special and not be putting that distance between you both.
If he reminds you of your ex, then clearly that's not a good sign, and if you're not yet over your ex, then maybe you need more time to yourself before you jump back into another relationship. Either way, if and when you do feel ready for a new relationship, from what you've said this does not sound like the right one for you. Find someone who is genuinely interested in you and wants to spend more time with you and is not taking this kind of interest in other girls... Good luck and I hope you find the right person, as I'm sure you will! :o)

calls you baby.

If he's a "hey babe" kind of guy he probably is...

You install the DetectPlayer app on your smart phone. It records a man audio and visually when he talks to you, then analyzes his speech, voice tone, body language to identify patterns consistent with players, has a 70% success rate and a low false positive guarantee.

Nah, I'm just kidding. You have to watch his actions and see if they are consistent with his words. Sadly good players can make a girl feel the most special on the world. But players are seeking sex, to add another notch, and they are not patient about it. If they, even while being nice to you, often push for sex, it's a good chance they are a player. If they spend more than a month with you, without at least and indication they'll be getting sex from you, they're probably more likely to be sincere. But, in the end, people are tricky and there is no surefire way to detect players.

Lots of girls on his Facebook gushing over him? That's a bad sign. Him hitting on and staring at girls left a right? A bad sign. His history of short-term relationships, or no relationship at all? A bad sign. Him reminding you of your player ex? A bad sign. If he's as hot as this other girl says he is, he's probably using that to his advantage with multiple girls. The hottest men usually are players. Not always, but the odds are good that he's not in it for commitment. You've said by your own words that he worries you. Time to get out now and find another guy who doesn't appear to need constant conquests if you want to have a committed relationship with a man.

He calls you all those cute pet names so he doesn't get you name mixed up and call you the other girls name.

This guy sounds like a player, IMO. Just really flirty.
