She seems to think I am going to drag up all of her indescretions and all that she has done to hurt me over the past few months.
But I fully intend to say something along these lines, when asked.

'I accept everything that has happened did so because you were unhappy in our marriage. I didn't realise things then that I really should have and obviously you had been unhappy for a long time.
All I can do is apologise for not doing enough to look after your needs in the way I should have. I realise now that there were so many things I paid no attention to when I should have. I can't change what has happened in the past and that saddens me.
All I can do is continue to be the best Dad I can be for our boys and I hope you find happiness in your life'

Does that sound too weak or forgiving?
Any advice on what I might or should say would be appreciated.
