I am sorry for misunderstanding.
The dynamics?
The best dynamic is praying and trusting God. Every single couple story is different from everyone else's. The only common denominator in successful Catholic marriages is that the man and woman trusted God to find their match.
More evidence of a worldly infection. No, that's the тαℓмυdic notion of "bashert" that your one-and-only alleged soulmate is assigned to you before you're even born. Too, the classical pagan myth of the tragically divided androgyne, as described by Aristophenes. ("Explain!" she pouts. Sorry, don't expect spoonfed Cliff Notes, research it yourself, you can do it.)
Don't forget about God's permissive will, unquestioning belief in which is the trait of genuine Catholics, not of heretics or the lukewarm. Sometimes God allows us to suffer a difficult spouse as a thorn in our side, as a cross to carry, in order to purify us. Why might might not ever be understandable in this mortal life, but we accept it no less. Ask your husband.
