feeling betrayed

i told her about this site and she went on and read it all and even posted about me like i wouldnt know who she was talking about. why do i feel betrayed. my councelor said its my fault but this site has saved my sad ass many times why wouldnt i tell her about it. but why am i so hurt that she wrote on it. i helped her clean for few hours other day because housing was gonna fine her because of dirty cluttered unsafe apt. when her kids got home they flipped out on her calling her every name in the book breaking mirrors. one ran away for a few hours. her daughter called her a very vile name. so am i a bad person cause i wont go back there. cause i will loose my temper. she needs me now but i cant deal with that. they have no respect for her. i see so much of myself in her and it has helped me grow stronger and realize my mistakes. im wiped out keep crying cause miss my sons so much. running away with daughter to visit family for the weekend and hopefully it helps both of us.
