I can so understand this situation a lot! I was abused by my step dad from 9 years old until i moved out at 19..... I told my mum and she ignored it and said it must be a bad dream. I have been teeling her on and off for years about it, to the point i ended up in the care of child services. I was silly enough to want to go back to my mum as he wasnt there, however he moved it and it started all again. She then came out with excuses like i look like her when they met, she even asked if i enjoyed it!? She came out with so many excuses i will not bore you with them.
Anyways its hard when you feel that the person thats suppose to keep you safe just cant seem to care, and seems to put him above you. My mum is still with the guy even though she now thinks he did it and has begged me not to go through with it...

You really need to do something about it, i know its hard, im going through a court case atm. The date is for the 24-28 November so only a few weeks away..... hold crap!!

Surely because of your abuse if you spoke to someone they may be able to help find you accommodation as they have to keep you safe and well? depends on where you live...

Hope this has helped to say you are not alone, and that you can be strong enough to fight for justice xxx
