You get in a relationship to LEARN how to love each other, you're not suppose to automatically know. People assume this and are too quick to break up

Relationships are like learning a new language. You start off clumsy, saying the wrong things, misunderstanding each other, but over time, you start to get it. You learn each other's rhythm, how to speak each other’s emotional language, and it gets easier.

This means you have to both patiently teach each other how you want to be loved and you also need to both be receptive to what the other person is teaching you & act on it.
