WC: This guy TURNED YOU IN TO THE ELDERS, like a snitch going to the Gestapo, and you are going to have lunch with him? WHY?
Ooohhh. I missed that part.
In that case, I totally agree with WingCommander.
When a person shows you who they are, you should believe them. I didn't realize this is the jerk who gave you so much trouble, Raven. By going for lunch with your step-father, you are repeating past victim patterns.
If you don't want to be a victim, you have to change your behavior. He won't - you have no indication that he has changed and any little thoughts you have about this being a warm and cuddly reuinion is simply wishful thinking on your part - exactly like a victim behaves.
Don't want to be a victim anymore? Then stop thinking that someone, who has abused and mistreated you in the past, will change. "Oh...it will be better this time..."
If you still desire to have a relationship with someone who has treated you so badly...then I guess you still have some life lessons to learn. Keep trying...it is hard to stand up for yourself when you don't realize how strong you actually are.
You made your post looking for advice so here is my advice to you - make up an excuse that you are busy if he calls again and then go out and do something nice for yourself. With people who don't try to trap you back into their deceitful lifestyle.
You will remain a victim as long as you keep acting like one. Going for lunch with this guy is victim behavior.
