Some people just don't know how to do it right. Many have not seen normal relationships and all the ideas about relationships from Hollywood films. But life is not a movie, not a fairy tale. And relationships are not just: "Let's meet!" or "Let's live together!". You need to work on yourself, you need to learn to listen and understand your partner, to discard pride. You need to understand that a quarrel is not the end, and first you need to talk, figure it out, try to solve it.
