Hey Bobby hang in there.
I have a lot of those days too. Every morning is the same where I can't believe this is happening to my family. You are in the right place. You will get stronger as time goes on. This takes so much time that it is hard to believe that it can get any better. This is precisely why you have to work on YOU. That is a tall order.
Working on yourself when the environment stinks is easier said than done. But you have found yourself here. You are given the tools to help you get through. It is great that you keep posting.
To me you seem like you are getting stronger although I bet you don't feel that way. Your wife, like mine, is wayyyyyy out there.
It will be a while before your wife looks within herself to find the answers she is looking for. If she does not look within herself, she will never see what she needs to see to move forward. You have the upper hand. You have a daughter and a history with your wife that will help pull things back together when your wife decides to look within. I see you registered back in February. That is the month that I got the bomb. I know now this started way before then as I look back. I am guessing it is similar for you. I have also known my wife for 30 years and I see your sitch very much like mine. Again, hang in there. There is much work to be done and you can do it!!
