Mixed Up Work/love

Hi, I have now come to the conclusion that my wife is having a fling/relationship with someone else.
We have a business, home and no kids together. If we split up it would mean moving out of the house into a smaller property and possibly losing most of my income. I don’t want to lose my wife but she’s slipping away from me. I don’t know what to do! I feel I just need holding tight.
