You need to CONSCIOUSLY change the internal dialogue in your head when you look at the photos of your daughter.
Instead of looking at the pictures and thinking this is when he was knee deep in his A, you need to look at the pictures and OUTLOUD say how beautiful and precious your daughter is and how special that day was when she came in to your life.
DO NOT let his A rob you or your daughter of this special day.
Concentrate on the POSITIVE of your daughter and that this is the anniversary of her birth.
Meanwhile, let your WH know you are triggering.
