Boundaries of Father/Daughter Teen Relationship?

What you are describing is totally inappropriate behaviour, so I wouldn't feel at all guilty at telling him to stop. Say to him that you're not a child anymore, and he needs to see you as a woman, and stop touching you. You are doubting yourself because you were abused when you were younger, so you think you're over-reacting. You're not over-reacting, he is really overstepping any normal boundaries. I bet he doesn't do these things in public, because he does know he shouldn't. It sounds creepy to me, but I'm uming you know him well enough to be sure his motives aren't as perverse as they sound. Tell him to stop it, anyway.
