I suppose that is the trick.... how do you do the right things when it is emotional and your life.
Try viewing your situation like a movie... and what would you be thinking about your character ... what would you say to your character?
Or this thought exercise -- you are 50 years old, confident comfortable and happy. What would think about how you are handling current situation?
It is hard and it [censored] when it is you. Now you have to man up-- try one of the two thought exercises above. Think it over and over everyday for hours. Now let your wife go - let her go. Give up emotions that are inside you about her.
Ok now you can be polite when you talk to her like she is a cashier at a food store but you are not going to lose sleep over what they say.
Best to let her go like she is not coming back... sure she may come back but guess what.. more work for that too. Now that she has been with someone else and the lying...
If you can truly let her go and GAL-- that is your best option for all good outcomes for the future. You will get through it and think about 10 years from now-- what will you think about how you handled it. Do this every day.
