Welcome. Sorry you are going through this. A couple of things.
Read the 37 rules. Also, because you both went to counseling in the past and improved and then degraded, I feel your wife isn't going to accept your 180's at first. Remember you have worked hard before and improved but things still got bad for her in the long run. This means your changes need to be real and lasting. Consistency will be very important.
Try not to focus too much on the house, finances, and such when talking and interacting with her. Now is not the time to share how you feel to get that comfort and support you are used to. NOT sharing your financial concerns might be a very big 180 for you. I am just speculating here so take what I say with a a grain of salt.
