Fights are normal and healthy, IMO. Never having a disagreement or argument would be very odd. It's what happens next after the fight is what showcases strong and loving relationships. You can talk and discuss the issue and work it out. Or in my case, I say something dumb, my wife laughs, tells me she can't stay mad at me, and we both giggle and forget what the fight was even about. Sometimes I fuck up. Sometimes she does. Admitting you were wrong and that you want to move past it means that you care about the relationship, and realize that in the grand scheme of things, this is just a tiny blip in what's otherwise been many, many years of sheer bliss together. 💜
