my moms bf

does my moms bf have the right to ground me? Honestly I'm pretty traumatized to what he's done from the past he didnt physically hurt me but it was verbal. There was fuck ton of drama cause he invaded everything, my phone, me watching porn, I can't even watch porn cause it blocked, I can't do No caller ID idk why. This phone is like tapped by him. I feel so exposed I am 17. He helps my mom, I don't ask anything from him I try to respect him but I just have this grudge towards him that won't go away he's been in my life for 4 years but I just can't seem to accept him, I can't let go. I have this resentment towards him and I've always wanted to move as soon as I'm legal age because of him. I love my mom but we always just clash.
