Is it wrong?

So I just turned 16 (f). My father has a friend that has visited our house since I can remember.

He's really kind with me, and even gave me a laptop for my bday (had broke mine) He's always there for me. He's on his 40's. Last night he said he liked me, but he always says it, so I said I liked him too, but he kissed me...

What should I do? I don't wanna lose his presence, he has always been there for me.
