Wife files divorce after I confronted her 2nd EA

[CWOL]

DDJ,
I'm having trouble seeing a better future. Realistically, I see myself gored, with:

My WW sneering at me, carrying on with OM (I get a taste of this when I hear her talking to her mother or OM)
Half a paycheck (she'll even get half my bonuses or raises)
Half my assets gone
Paying off WW to keep the house I bought before I married her and 100% paid for by my income
Big chunk of money gone to legal fees
Mustering up confidence to date again at 47
Finding a woman I would want to date
Not seeing my son 1/2 the time
Not able to get the best for S11, whether it's private school later or college fund

The only positive I have left in life now is my S11. He does bring me joy every time I'm around him.

Can anyone help me get through these dark times? Am I missing something? I really don't see much future to look forward to.
