@jonhammsmistress great post.
My friends and her siblings ALL have different levels of anxiety and depression and she lays it at the door of her father.
When he was moody with her toddler one day she really went off on him and let him have, plus her mum.
She layed all the family's anxiety at his door for his moodiness growing up.
There was never a hint of violence just a very nice middle class family with all the trappings of a blessed life ruled by his sulks and moods.
After she let him have it, he never showed a hint of it again, (her mother was absolutely furious with him too) but she was low contact with both her parents as even being in his company as an independent adult brought her out in hives because of the damage of her childhood.
She describes herself as a hyper sensitive person to peoples moods and general atmosphere and she has low level social anxiety as a result.
She was a bright girl who has done well but she absolutely believes the legacy of her fathers moods was she never fully had the confidence in herself to meet her full potential.
Her siblings feel the same.
I remember her father as a sour man and we certainly avoided her home to hang out.
It wasn't until we were in our twenties and she was very upset when our other friends wonderful father died and she was devastated, that the full truth emerged.
Children absorbed so much.
The OP sounds like a great woman and thank goodness she remains tight with her family and they see him for who he is.
I reckon her mother has the full measure of him and will just be waiting for her to let them know.
Thank goodness she has that support on hand.
So many do not.
