It's so hard to just... forgive and forget

Last month, I got into a nasty tiff with my ex husband's niece, Jessica.  (Note: I will NOT call her my neice any longer. It pains me too much).
Her sister, Chelsea, was getting married.  And I was told that I was not wanted at the wedding by Jessica.
What got her so tiffed at me?   Because I told her the truth.   That her boyfriend, Justin, who is a drug abuser/user was locking their kids up in the room because he wanted to play XBOX.  And she knew this.
I heard it from someone that works with her too.  That she said that to this person.  I'm surprised that this person didn't tell her the friend, a cop, about it.

Jessica expects me to just drop it and get over it.    She even told my daughter at work more or less that I should just forget it and forgive her because I was friends with Ann, my ex sister in law after she and I had gotten into some tiffs.   Well... guess what?   Ann never hurt me like Jessica did.
I've known Chelsea since the day that she was born.  And the fact that I was told by her sister that I wasn't wanted...    It HURT ME DEEPLY!!!

I am taking a break from Facebook for a couple of days.  I am NOT going to stress myself out by going on there!!!

Why can't people see what they do?  How they hurt you and affect you?  She doesn't think that it was a big deal that I wasn't there at the wedding.  And the fact that she LIED to the Abbott family about WHY I wasn't there!!!!!  That makes it even worse!!!!

If she would just come clean with the Abbott family and everyone else about WHY I wasn't there.   And if she would just come to me face to face and apologize... I'd be able to just forget... and move on.   Like... THAT WILL EVER HAPPEN!!
