killingmesoftly, I too was abused as a child, by my stepfather, my mother chose to ignore what ever I sid to her, so much so I started to think I was lying!
Things were terrible from 8-15, when she finally put me into care, after I had him prosecuted for beating me up, (well, I had him arrested, then dropped the charges, because I didnt ant to upset her) she then married him, I wasnt invited of course.
For a few years from around 16-18 I didnt have any contact with her, then an exbf
persuaded me to contact her, so I did, it was always really hard and I was still at the point where I felt obliged to try, like I owed her something.
When I was 20, I found my real dad, he died 10 months later of cancer at the same time my mum had just split from my stepdad. I called her in pieces after I ofund out my dad had died and she came round to my house (I had a DD of 11months, and my exDP had been sentenc4ed to 2 1/2 years in prison a month before) She decided the day my dad died, and the one time I was really all alone would be the day to tell me she was getting back together with my stepdad, and that the reason they had split was he had left her for a 15yo girl, her friends daughter. I was so shocked, she was still convinced he wasn't a sexual predator, three weeks later, was xmas, I spent it alone. My 21st birthday was 2 weeks after that and she didnt call me to wish me happy birthday.
I called her at ten pm, asking where my card was, and why she hadnt called, told her to fuck off, and havent spoken to her since.
I had to deal with all this by myself, and found that after the anger, came acceptance.
First you need to realise that you were a child, so any guilt, has no reason to be there.
You need to remember that she was an adult and should have wanted to protect you, which she didn't, she made her choice, now you make yours.
Yes, She gave birth to you, but does that really mean you owe her anything??? No, of course it doesn't.
The best thing I ever did was cut her out of my life, the same way I would anyone who put my mental health at risk, or could possibly hurt my children in some way, she didnt care enough to protect me, so I can't guarantee she would protect them.
I think I read someone had reccomended CBT? If you can get some help in that respect then do, it is all about changing your thought processes and therefore your behaviour, I didn't have any help in that respect, but over time, I feel I have done it myself.
It ahs been 5years since I spoke to her now, 6 in january.
I've recently 'found' my cousin on facebook, and she has asked me to contact my auntie, yet I'm hesitant to, incase it brings that woman back into my life (I know my family think I was a troubled teen that ran away lots and rebelled etc, my mother always blamed me, and I'm not sure I can go through not being believed, again), so it's not something that will likely ever go away, but it's something I know how to deal with now. As will you.
Good Luck.
