Just a thought. Saviour of women, DA, etc..
Now ignoring the fact that you have an amazing memory (inherited by your eldest) .. if any of that guff written was true the first thing I thought was perhaps her mum was actually a victim of DV, very much reads like ' wife was cut off from family and support network, husband was absent and emotionally unavailable, arguments, wife ran away" .. sounds like you should have a day off using your mother as a whipping post!
Whilst you are at it, you should stop creating false memories I'm the same as you Rach and I cant remember that far back. I too had a traumatic childhood, I dont rehash these traumatic events day after day after day. I had therapy, I now have a very good life, like you say you do. I dont believe you if you really did have a good life you would leave the past in the past, because 100% they don't go together. You're so hung up on the past you can't be present, money does not buy happiness.
Also you should revisit that passage about mothers not being present, siblings raising siblings and take a long hard look at yourself. One day Betsy will be writing stories on the Internet about you.
