Fold? Come on. You can't control your feelings now. Just because you say or type "I Fold". Do you really think it will change how you 'feel'?
OK - it might, temporarily. It will let you feel like a cancer victim, they stop Chemo - all feels better, for a few days, weeks or months, then the route cause of the problem kicks in.....
Look guys I know this is absolutely horrible I am living your nightmare too - so many are). You will never control how your wife is. Equally she will never control how you are. You don't have to 'fold' to 'let go'. Even if you do fold you still have to let go. Don't you see? Its the same job you have. 'Let go' - call it fold call it 'being done' I don't care, but don't close the door. Just leave it a jar or let a light shine through the keyhole - whatever.
It's hard, I get it. Really got there then crashed recently. Getting back in the saddle again and already feeling more positive. Gym, work, GAL, make plans for you and the kids - cuddle them. You know what works.
A different spin. How do you feel about someone else right now? Could you walk into a bar and be the confident guy you need to be to win their heart - is your heart is in it? If you could, could you be the guy that knows, for sure, that if your W (not WW) came back that you would not be tempted to drop your new date like a burning coal? Answer either of these as no and you are not detached.
Focus on 'let go' not fold is the best advice I can give. Another point, you don't her at this point in any event. I copy & post something I typed the other day that may help.
