I found the book "The Psychology of Romantic Love" pretty insightful. It gave me a better view of what love means culturally.
Also there is a saying which goes in the direction: to love, to hate, or not to care. It's great to love, sometimes there can be hate/anger/disagreement, but you know the relationship needs work if you stop caring about each other in certain situations. So whenever one falls into 3, it's time to think, talk and do something. It's not always critical, but it shows an absence of attention for each other.
And my grandmother used to say, sometimes you can be very angry at each other, it's important to discuss it thoroughly, maybe even loud, and then leave it there and go on.
