SDs - delightful creatures.
I met my DH long after he had spit from his EW.
We have daughters the same age, they were both 6 at the time.
His daughter was trained to hate me, by her mother, Her mother was already in a relationship and was pregnant at the time.
For the first four years, the SD was used as a lethal weapon. It got so bad that we jumped ship and moved 200 miles away to be near my family. Crime of the century.
In that first four years, DH was only allowed to see his DD when certain rules were applied to by him. His DD was trained to report ANYTHING and EVERYTHING that we said and did. It was then used as a weapon.
In that 4 years he saw he 7 times, even though we all lived within half a mile.
So we moved.
I then became 'the other woman' who had split their marriage up and stole her dad.
DH drove 400 miles each way, once a month, to see her. That lasted one year.
She very occasionally agreed to stay with us, for Easter or Christmas. It was a living nightmare.
All direct contact stopped when she was 18. Her choice. She is now 28.
My DH has NEVER changed his mobile phone number, still has her on FB (think she has forgotten that). Through FB he knows that she has a fabulous career, is married, with a DD of her own.
He walked my DD down the aisle, and is DGD to our GC.
But he would give the world to have contact with her. He never stopped trying and he never will.
