I have been telling you - sometimes confusingly - that the previous old life does not matter and what happened in the past stays in the past. Like a clock we move forwards, not back. If you spend time worrying about the past, you cannot move forwards into the future.
I want you to know that when and if I see your daughter, then I will not see anything in her other than her mother. I will not see the biological father of her in her eyes - only you - the important bit.
Some bad things that happen to us in the past have goodness in them. I really do not like my ex-wife, but I would never have had my boys without her - same as you and you daughter. So, in a way we both have to feel quite grateful for the badness in our past.
The future is what we make it. Y es you and me. Maybe get your ex to marry my ex and whilst we will live in happiness with our children - they could stew in their soup of bitterness, deceit and self preservation.
