Here we go again

Well at least that lasted a little while, well for my granddaughters a few months, for my grandson she hung on a little longer.  By June of 2011 Missing Mom had left the babies again, except this time the baby's daddy took the girls and DSS placed GS with me.  It lasted 3 weeks because DSS did not want to take custody of him and would only investigate the claim of abandonment.
For months I supported her in her fight with babys daddy, paid for a lawyer, gave up the guardianship because I believed she had really turned a corner in her life, that she wanted to be mama, that being a mama was way more important than drinking or just tending to her own needs.
WRONG!! WRONG and WRONG!
So the babies have not seen her since July 2011, and grandson was being dragged along through her sometimes brutal lifestyle of violence and drinking.  We have not talked, missing mama and I, I had enough of her sucking the life out of me, and put my foot down.  So she would let me see grandson maybe once a month for a few hours, until a month ago, when she let him spend the night!!! I was so happy!
This weekend GS called "unci I want to visit you" of course you can!  Can I spend the night? of course you can!  I was so excited to be able to spend time with my now 5 year old grandson.  Well Sunday comes along, get a text "my car broke down can you bring him to me?"  Of course I can.  We arrive, no Missing Mama!!!! He is again crushed telling me "Unci, what am I gonna do?" crying the whole time.  I waited till Monday afternoon no word from her.  I went to the courthouse and filed for guardianship again.
God, haven't I been here before! I never wanted to be here again!!! But I will not stand by and allow her to do this to him.  I don't know if our relationship will ever be the same, I love her but I can't stand her decisions she has made, or that she does not give a thought to her children, that I will never ever understand.  So our hearing is later on this month, and I know it will be a fight, she told me today she does not need help and she was saying goodbye to GS before she goes to the city where she lives, I am wrong and she is right.  That is how sick she is, she really believes its ok to continue to leave your children.
When they dropped him off on Saturday, there was mention of an ear ache.  I had to give him pain relievers all weekend and a heating pad.  As soon as I got my order, I took him to the ER, ear infection, pink eye and some kind of fungal growth on his head!  Lord please help me through this!
