Getting fed up with some family

So I decided a few months ago that my daughter and I will have nothing to do with a certain family member because I do not trust this person at all. I’ve caught this person watching me take showers and change clothes through the windows when I was younger and it took me years to finally tell my family the truth. This person is of course lying and saying it never happened. I have made it absolutely clear that I want nothing to do with this person and I don’t want to ever talk about this person again. My family is still trying to get me to go to family events with this person there and even talk to me about this person so I haven’t made myself clear enough like I thought. They even had the audacity to ask me to let my daughter go to these family events without me. I literally have no idea what to do.. I’m honestly hurt because i feel disrespected by my family. Knowing my wishes but going against them. These are close family members too btw. It literally eats me up because I’m trying to move on and forget about it but I can’t with everyone trying to get us to go around him and even asking to let my daughter go by herself. She’s only 4 years old. I have nightmares about this person trying to hurt me and take my daughter.
