have i been making mistakes too long

[tkdmme]

I was reading on of sandi2's articles about the difference between WW who is having an affair and one who isn't. She mentioned that the approach should be different. Can anyone help me with this. My wife is not having an affair. I know this because she works for her brother and he is against the divorce, She comes straight home after work, and my gut is telling me that she is being faithful.
Is the approach to this situation the same as the approach to someone who is having an A.
