You did great not reacting to his "denial" and lack of willingness to take any responsibility
What helped my D at age 12 when her dad left(she is almost 24 now) was sitting with her at the end of the day and just listening to her ..This actually began a great connection with us and we still talk everyday and she shares her life, her goals and dreams with me and her pains
Just listen to her and try to say nothing, just nod and be quiet--validate her life and pain and nod
My xh never wanted to talk about anything either-and many
hang in there
