Leela- My wife and my heart goes out to you my friend in what you suffered. I had a strict elder dad who was very harsh as well. I admire you so much for moving on and creating a wonderful family of your own with your children and companion. What you have with them is priceless . It means everything. I feel you've made a good decision not to give your dad anymore of your time. You owe him nothing - because he gave you nothing but misery.
It may be that just sending condolences to your mom is the way to go, but to get involved with these emotional vampires who sucked the power away from you when young would just put you back in a bad place emotionally. You have regained your own power again as an adult woman and you have moved on in a positive way in life and your loving family that you live with now is what is important. Honor these ones that love you- give no quarter to the former family that dishonored you. Forgiveness is overrated. Forgiveness doesn't mean much to those who feel they did nothing wrong. They don't get it. It falls on deaf ears.
Wishing you and your partner and children all the happiness in the future. We are all here for you on this board. Take care, Sincerely, Mr. Flipper
