I can only give you my experience.

In my state, spousal infidelity has little or no real bearing on alimony or child support awarded. It is grounds for divorce and that is about it. So your situation might me different.

I spoke with a private detective when I found out. His advice to me was to decide for myself if knowing details would really make things better. I know for myself they would not. Knowing that something is going on was good enough for me and acting on that was key.

If you suspect a PA you are in the right place. Something is wrong in your marriage that needs to be looked at. And I've found the advice here to be very helpful. Read the books. Make changes in yourself. Do what is suggested.

It's like the old saying - a social drinker doesn't sit up at night wondering if he is an alcoholic. Someone in a healthy and happy marriage doesn't sit up at night wondering if his wife is in a PA. Something is wrong. The change begins with you. Knowing details won't change what you need to do to save your marriage. They will only give you reason to give up in self pity.

Just my opinion though.
