Sleeping in same bed as a child

So I got told today from my ex that I'm currently pregnant by that because I don't have a father, mind you I've known my father my whole life, went to his house every other weekend and lived with him for a couple of years lol, that I don't know how to properly distinguish a how a man should act towards their child and I'm sick for saying something is sexual. But there's no reason a grown man should ever sleep in the bed naked with their daughter who isn't a toddler. She's 8 years old. I think it's sick and nasty and that's not normal father daughter things
