I, Well, your h hit the description right on the nail head! Yes, he's have a huge crisis right now.
Everything you posted is very, very typical of someone in crisis. I'm not surprised that he's brought up things from the past and yes, he's trying to compare and justify what he's doing w/what he thinks took place years ago. You know better, so just let those comments roll off your back.
He's got a lot of issues to deal with and you will need to choose your battles when dealing with him. Your daughter is your number one priority and he needs to hear what you have to say about taking care of her.
Trust me, what he is saying about how he feels....he really does feel that way right now. His perception of life is so very dark and grey. Months from now, even years from now, he may tell you it wasn't the way he remembered or what he said to you. They always lash out at the ones they love.
I, you are moving forward, but you will take some steps back along the way. Do not feel that you are stuck for you are not. You are right where you should be at this moment.
Hugs to you and your family.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
