I don't know if I'm making more of this than it is but my FIL is always putting his hand on my lower back and rubbing it. He also rubs the side of my face and pushes my hair away from my face. I almost feel like I've taken the place of his wife in his mind since she passed away suddenly 3 months ago. He has Alzheimers so probably doesn't think this is inappropriate and maybe it's not but it makes me so uncomfortable. I don't want to scold him for doing this, but what else should I do?
