I'm not taking about general out of a book type stuff, but in real life from your actual relationship, what is the ingredient(s) that make it successful?
I'd say mine is give and take / compromise, which I'm expecting to be repeated within the thread, but also interested to know other strong points of success.
I'm referring to a sharing of working, household tasks, finances and mutual understanding of the want and need to each have time to ourselves and together.
