What shall I do about him ?

So There’s this boy, he seem really nice and understanding. He has came up to me comforted me when I’m in need, cheered me on until I achieved my goals and everything. He asked me out the other day, and I said let me think about it, he said he doesn’t care how long the wait is, I make him a different person. So I went rooting and I’ve asked my friends who know some girls who have info about him. They’ve all said he is a player and does anything to get in a girls pants, and that I shouldn’t go out with him. Me personally, I don’t see him as that I see him as the opposite to a player but I’m not sure... shall I go out with him or not?
