If I am not going to my husbands daughters graduation.... because some bitch is going instead of me..... I'm going to leave this family...... some bitch that they knew a long time ago and used to go out with my husband and she cheated on him and blah blah..... seriously..... I'm furious..... the daughter was the one that invited her and the daughter and I used to get along but she doesn't like me because I tell her to do her chores and not disrespect me.....
