Girl thinks Im not exactly who I am and more...?

There is this girl that I have recently become friends with and she and I have not really been going so well all of a sudden. We talk and have fun chats here and there and we are jokingly "engaged", but the scary part is I think I am starting to like her. I am fine with that, but recently she was sick so I didnt talk to her much and she doesnt respond her IMs a lot anymore since she got better and we havent really talked much, but I kinda seem a lil needy by asking her where she is sometimes. She told me that she doesnt really like how I am not really myself aronud her and she thinks Im a player and even though I tell her the truth, it still comes out like I am a player to her. She thinks Im smooth too but she talks to some guys too as friends and it kinda makes me feel a bit scared. We arent going out or anything, but I like her now but we just turned friends and she isnt more popular than me or anything, we hang around different groups, but we just arent the same. wut do I do?
