The Bitch

I don't swear much, but I cannot think of my son's soon to be mother in law any other way.   She does not like my son and has been nothing but cruel to him since he started dating his girl.
I can't go to the wedding.   My son is LDS and I am not.   Her family is so the bitch can go.
My son is upset that he will be surrounded by hostile people who don't like him on his wedding day.   I suggested they tell her parents they couldn't go since the bitch refused to speak to my son for 3 months and banned him from her home.   Well they were told so now they are trying to play nicer and are invited.  
They gave them the rest of the wedding money the other day, but as they handed it over told her it wasn't too late to change her mind and not marry him.
Yesterday I found out there is a mom's chair at the wedding.   Mine will be empty and she will have her fat butt in hers.   My son will  have to stare at an empty chair and I will have to wait outside knowing he haas no one in there.  I have a friend who is LDS and she is going for me.  I don't know whether to have her sit in the chair for me or not.
I am not handling this well.  It isn't so much that I can't be there, but that the bitch who hates my son can.  She will share this special moment and I will not.   I am petty and vicious and I hate her so much.
I can't stop crying and I need to go to work....
