I had a great Mother's Day with my fiancé daughter and little sister in law. But it hurt to say that I cry some of the day because I'm going to be take my own mother in law to court to get custody of her daughter and I really don't want to do that but it the best from my little sister. Because her own mom doesn't give a shit about her. Her mom rather be out partying and getting drunk then coming home and hanging out with her. But when she doesn't hang out with her she take her daughter to home where there people drinking and getting crazy. My mother in law doesn't care if something happen to her daughter. I have become a mom to her already I'm the one go to all her school meeting and school activity. It break my heart when she calls me mom and she doesn't even want to speak to her mom no more.
