How do you tell if a guy is a player or seriously likes you?

Make him take you on a few dates. If he's a player, he'll buck and leave.

Tell Him how you feel. Guys are simple minded. They don't like guessing

yea! kudos to the dude under me!
he explained to every extent

this question's asking 3 things at once and doesn't give enough details to answer any of them in any helpful way.
From what I can tell, he likes you. Obviously.

And why do you want to tell him you like him if you're worried he might be a player? You're moving too fast but you're confused at the same time. I think you need to think this through yourself and make sense about what's going on inside your mind.

He should say it first , in that case you'll avoid the embarrassing if he don't feel the same ,
plus he's the guy and he need to make the move .

deffinatly don't put yourself out there. by what you're saying, he seems like a real ladies man. but if its anything he'll hate its you not being all over him. play coy a little and make him come after you. it'll drive him crazy and make him wonder why you won't do what every other girl does. and if he doesn't try, he's not worth it.
