Is my relationship normal?

Tatyana
How do you know that when you and your significant other get into a bad argument that that's not God sending you a message that it's just not meant to be? To what extent does "everyone in relationships argue" go? How do you know if you're meant to be together or not? Me & my boyfriend don't argue excessively but when we do, it's not pretty. When we are good, we're great. But when we are bad it's terrible. Advice? PLEASE
