Just make sure you are doing 180 on any and all toxic behaviors.
I know you said you felt detached when you were doing hobbies. But like it has been said before, there is a way to do hobbies and not ignore. No, you don't need to go run and try and pursue her.
Please don't go full charge like you are trying to date for the first time. You need to show that you can manage your hobbies and your family. You can't just drop your hobbies, because like steve says, this is about respect.
If you dropped your hobbies and went into super husband mode, she will feel its fake. So you need to make sure that you are taking care of yourself as well. Do you workout? If not, do it.
You just need to be present. If you are in a room and she is there, or even if she isnt there, and something needs to be done, just do it. Dishes etc, whatever needs to be done.
Are you affectionate with your daughter? You said you are a good dad, and I believe you are. But are you lovey dubby with your little girl? You are now focusing on yourself and your daughter. You need to make her feel like a princess. Make her feel loved, supported, comfortable, secure. Be super dad. Beyond super dad.
You will be bettering yourself and your relationship with your daughter. That is the point of DB. Then, this type of loving detachment from your W, will get noticed by her. Then, she may, just maybe decide its worth working on the M.
Just rememeber, you truly need to go from the thought of "I am going to do this so she notices so she loves me more" to "I am going to make this change or do XXX for me because that will make me a better person and will make me happy"
Or "I am going to make this change or take this action because my baby girl is going to love it and it will make her happy, and will show that I am a great father and will always be her dad and will always be there for her"
Its hard man. This is going to test your will more than anything in your entire life. But you will come out the end of it as a better person. You will come out of the end being a better father.
