If the wife feels in her gut the husband is cheating, I would think it's very sensible. Finding out if someone is cheating whether someone hires a PI or whatever is very important. I think the possible risk is accusing someone of something they are not doing.
This kind of obsessive thinking, the wondering and accusing, can become a horrible, painful burden. It's nice to trust the person you are with however, there are times it's just not possible. If a wife knows he's cheating but wants proof, I would definitely do it.
If you're the wife, it would seem sensible. If you're the husband, it would not. Like all in life, it's yin/yang -- 50/50.
There is NOTHING that is all good or all bad.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
