Was he critical & demanding BEFORE you got married? Was this red flags before the wedding that you just didn't pay attention to?

Wonder if his previous wife would tell you.....yea, that's what caused the first marriage to fail.

Second marriages have baggage if the cause of the marriage failing was never resolved. Marriage counselling is about the only solution. If he is unwilling, I would write off the marriage & him as not being the kind of guy anyone should be married to.
