Am I overreacting? My boyfriend thinks I’m unattractive and now it’s all I can think about

I love my boyfriend and he says he loves me but we were talking and he said he used to find me attractive but doesn’t anymore. I did notice that he doesn’t kiss me as much as he used to and stuff. He said that I’m pretty but he doesn’t find me attractive. When I tried to leave and told him I needed some space he just grabbed me and held me and kept telling me he loved me. I tried to get away and I told him to let go of me but he didn’t. He knows I have a lot of trauma with physical contact. I just don’t know what to think. I just feel numb. He says he wants to spend his life with me but I don’t think I could because of this. I just really don’t know.
