I'm essentially no contact by choice and design with both my parents (who emotionally abused me severely), and have told them I will only contact them with a short text to wish them well on holidays and to alert them to important changes (address, name, marital status, etc) but that is it. Otherwise I will leave the door open to a genuine attempt at a non-abusive relationship, but I do not have much of any hope in that.

Of course they also took a lot of my family with them, but you win some you lose some I suppose...I just not continue to take the pain of continued contact anymore. I held on so much longer than was healthy to do.
