Your sister sounds narcissistic and is manipulating your parents

you're already the bigger person. just move on.

While you have the scissors out, why don't you cut out your parents, too?

Blood family ties do not mean you have to stand by them.

forgive her. not for her but for yourself. you don't have to go have drinks with the bitch, but holding on to this anger will give you explosive diarrhea.

Ah Hell NAHHH! Be angry. What a horrible breach of trust and love on so many levels.

You are an amazing person. If this happened to me, I think there might be bodies.

They aren't wrong, but they should understand that it takes time to forgive.

Pick better boyfriends?

I guess we can see who the favorite sister is.
