Pervy stepdad *update

My stepdad makes me uncomfortable. He always gawks at me and I hate to dress nice because I can hear him make weird noises and say stuff like “goddamn she looks hot.” It’s been happening since I was 14. I’m almost 18 now and I’ve stopped telling my mom because she just says “He does that just to aggravate you.” He’s also been my stepdad since I was 7 and I’ve seen him get drunk before while camping and say horrible things about girls walking by that were probably no older than 13. Just had to get that off my chest since I can’t tell anyone and my mom won’t listen.

*update- my mom keeps defending him. It’s gotten worse. Idk if she defends him because he’s batshit crazy and would probably kill her if she left or because he’s going to pay for me to go to college or because she really thinks it’s not a big deal. I’m going to try and move in with my grandparents or maybe rent a place with a friend. I don’t care if he doesn’t pay for my college, I’d rather just get him out of my life. It’s ruined dating for me. I’m not “allowed” to date in HIS house. Whenever I go out with friends and come home late (9 is late according to him) he always accuses me of being a whore or drinking or doing drugs. I can’t take it anymore. I have to get out. Thanks to everyone for their replies and for just listening.
