@MrsNotNice sorry for the delayed response, I have been told I'm compassionate and thank you for such a lovely compliment, but honestly I think it was driven by loneliness, she and I never had an equal footing until I too became a Mother and I never really got a replacement mother figure.
Her Mum, my Grandmother is a narcissistic, alcoholic cold and manipulative woman, she and my Grandfather raised me and my full brother and sister from babyhood but I moved out as soon as I turned 16 as I was always the scapegoat child with my Grandmother, my Grandfather had not long since passed away and I was the "fall-guy" for all of her psychological issues.
Whilst my own Mother exposed me to a very dark side of herself it was never directed at me really, I saw violence because she allowed herself to be abused at the hands of her various boyfriends. I saw her own alcoholism and as a child it scared me, but as an adult I think I sort of understand that she was perpetuating all of the negativity from her own young life.
I was an after thought to her when I was young, it wasn't until she met her current partner and settled down that she broke her own cycle of mistreatment, then when I saw how hard she tried (from a distance) to be a good Mum to my half brother and sister I felt resentment to begin with, a sort of jealousy that they got the attention from her that I never could. But again, I grew up, I admit and she acknowledges that she let me down in many ways. But I could either choose to remain NC or give her a last attempt at a relationship. I have thought since I lost my Grandfather (not exactly a saint of a man but the only Father I ever had and he tried his best) that life is too short to focus on negativity, doesn't mean it doesn't affect me of course, but if I can choose a path that lessens some of that childhood pain, then why not try? But this is something that took over a decade to contemplate and only when I fell pregnant and thought (at a particularly vulnerable moment after I'd discovered I was having twins) that "I want my Mummy" - so I thought give it one more shot, but this time, on my terms :)
