I need help! I haven't spoken to my mother in 20 years. She left my dad for another man and destroyed my family in numerous ways.

Seriously. She caused a suicide, selfharm, and longterm mental health issues in my direct family.

Her brother (my uncle), whom I have never met or spoken to sent me a friend request on facebook.

I'm certain he's being a go between for her.

I need the most diabolical ways to fuck with these two.

I was thinking of implying I am willing to start contact again, and then ripping the rug out.

Anyone have any better ideas?
