Suspecting child’s Father cheating

I’ve never hired a PI before. But have you thought if you were to hire a PI, and your husband really is having an affair outside, what are you gonna do? Are you hiring a PI just to prove to your parents in law? Tbh, i think you should try talking to your husband first before hiring a PI and getting those incriminating photos just to “prove” to your parents in law. At the end of the day, the marriage is between you and your husband. Not your husband and your parents in law. There is no need to prove anything to them.
