Is he being sincere?

Once a player always a player, or what do you think? I’ve fallen for this guy at work and I think I’m falling deep. He’s just like me personality wise so we get along incredibly well, I love being around him cause he makes me feel so good! You know that feeling… As soon as he walks into the room I can feel this tension between us. Now, nothing has happened between us. He’s told me about his past, and how he used to be a such a PLAYER, and I can tell he’s telling the truth, because he’s a very smooth talker, good with girls. So he’s been telling me he’s been a major party animal, have had sex with lots of girls and have dated lots of women. Obviously he can’t commit, and he’s also told me that he finds it hard to stick to one woman.

Now the funny part: He’s married, but says it’s an open relationship kind of so obviously it’s OK in their relationship to meet other men/women. I dunno if he loves his wife cause he told me he did it mostly cause she wanted to.

He’s been asking lots of questions about me, if Im seeing someone, etc, also we’ve been talking about settling down and finding ‘the one’.

Now, I don’t know what he’s after. He is flirting with me all the time, and I know part of it is because he just wants to get into my pants. BUT, he also seems kind of nervous and shy somtimes, and he really seems to like me as a friend because he always light up when he sees me, touches me often, smiles at me a lot, asks me questions about what things I like to do, what music I like etc. A lot of the times he’s just staring at me, from distance, and when I meet his gaze he holds it. I have his phone number, cause he gave it to me. But I havent phoned him, since Im not sure of his intentions.

Im not sure how to act and what to do, I know he likes me as a friend, because we get a long really well, and to be honest I think he likes me most of all coworkers at work cause he’s always really happy when he sees me.

But what’s up with the flirting?? What do you think he wants from me? We’re friends, but we’re also flirting, but on the other hand he’s married AND a player. Is he playing me? But why would you want to play a friend?
