I somewhat agree but it depends. In my current relationship we sometimes argue and rarely we even fight but it's because we truly care for each other. I know this man loves me and would take a bullet for me. (I'd do the same.)
In my previous relationship my partner and me would almost never argue but I was miserable because that person would never want to solve anything.
Now with my current one I bicker, I play I argue and it's the healthiest relationship I've ever had.
Please, don't just give an advice to break up under a post that is about venting. You don't know this person (I don't either.) It's insensitive to immediately jump to the worst possible conclusion and tell them to potentiality ruin their love life.
I've seen too many people break up over dumb things and then be miserable for years because they lost their soulmate... A break up can be a remedy but it can also be the nail in someone's coffin.
