THAT is the key. Not lovemaking, and not arguments.
It is respect.
Without mutual respect, I don't believe you can have a happy marriage, no matter how many times you have intercourse or how many times you argue.
My wife and I are getting close to our fiftieth. I’ve got all bases covered. We respect each other, still get it on regularly, and rarely argue.
Absolutely, I could not truly Love my Wife if I did not respect her. But intimacy is important in my marriage -my Wife is not my “buddy” - to me it is why man & woman were made for each other.
