My little sister got a creepy boyfriend. 

She shared tmi about their sex life every time she talks to me.

When they were in town for holidays, we carpooled to family gatherings because I didn't have a car. Every time they came over, they shared more tmi and did something disgusting in my home in front of me. They dry humped on my roommate's bed, claiming they were helping me stand up for myself by forcing me into an awkward position, but really they were being rude and traumatizing me for life.

They even fooled around in the parking lot where I was letting them park their SUV.

I've told them to stop. They snickered and enjoyed my pain.

I told her I don't like her filthy trash boy. I've told other family members and they ignored me. It really hurt me that I've been singled out as not deserving any respect.

She married him and had a baby for him, anyway.

I took the high road and kept being nice to them in spite of how rude they are. I feel like I'm being gas lighted by everyone to think maybe I hallucinated the nasty sex stuff because everyone else treats them like angels even though he abuses his daughter right in front of everybody and the kid is turning into a sociopath that lies and steals and assaults people. 

I've been essentially shunned by the  family over time and had a nervous breakdown. It's best to be away from such harmful people, but the trade off is that I'm all alone with no support during any hard times.

It would help me out to hear that I'm not crazy, that I deserve to have my wishes respected, and that my voice matters.
