my life

my life is so unpredictable, one day it is miserable and the next i am down on my knees, my son is with a girl that he met at a friends house and he got her pregnant. she is the most evil person we have ever met. my grandson is now 8 months old and we hardly ever get to see him, my son has tried to live with her, he got a apt and she moved in with his son she tries her best to keep us out of his life and hides behind a bible like she is some saint. she has come into our lifes and has tried to ruin our lives..... i get so depressed how she treats my son as well as she makes it clear to us we have no rights. it is all about her mom and step father.  my husband thinks she is a curse from her mom having afair with a married man he is mexican. she is very pretty girl but inside she is ugly. i wish i knew what to do. my son is so afraid of losing his son. he is very troubled and with how she treats us.
