Covert sexual abuse

Trigger warning: covert sexual abuse

My dad's gaze has been creepy and I've noticed it ever since my body changed. I'm a grown woman now and for years I would catch him looking down at my chest. I once bent down my dress sort of slipped down and he was staring at my cleavage (I was a teenager). I've felt really uncomfortable around him and my mom invalidated me when I told her. I hate taking pictures with him and just being around him in general. My mom plays dumb and will say things like, "come on, why can't you just take a picture? Take your jacket off," even though she knows why I dress in layers and don't like being around him. I've told her many times. I really want to call out my dad on it. He's very emotionally abusive and has absolutely destroyed my nervous system since I was a child (I have debilitating anger and anxiety that has manifested into chronic issues). I know the gaslighting and screaming match that will ensue when I call him out and I'm really scared to. I also unfortunately lost my job so live at their house and depend on them for a roof over my head right now. I don't know what to do, I can't take it anymore and really want to call him out, but am really scared.
