Welcome to the boards. I'm sure the posters here will help you immensely as you try to sort out this difficult life stage.
You've done very well over the past five days and your connection to God, working out and not drinking are HUGE life changes.
The journey we are on is so often referred to as a rollercoaster and you can already see this with your wife's warm, warmer, cool, cooler behaviour. She is probably really confused, especially as she sees the beginnings of change in you. She doesn't trust the change though, so you have to be consistent and keep at it eventhough it may not get the response from your w that you were hoping for.
You were right in your assessment of Tuesday....don't react. She's in a 'fog' at the moment and you don't need to chase her into the fog, rather you need to be the lighthouse. Be exemplary in your behaviour and notice the positives and ignore the negatives. The 5 Love languages gives a good story about that.
There's loads to be learned here on the board so read, read and read. You'll find wonderful support and help right here.
Don't forget to read and re-read Divorce Remedy, too!
