The partner truly best suited to us is not the one who miraculously happens to share every taste, but the one who can negotiate differences in taste … - Alain de Botton

At the beginning of human history, as we struggled to light fires and to chisel fallen trees into rudimentary canoes, who could have predicted that long after we had managed to send men to the moon and areoplanes to Australasia, we would still have such trouble knowing how to tolerate ourselves, forgive our loved ones, and apologise for our tantrums?

Albert Camus suggested that we fall in love with people because, from the outside, they look so whole, physically whole and emotionally ‘together’ – when subjectively, we feel dispersed and confused.

"We seem normal only to those who don't know us very well. In a wiser, more self-aware society than our own, a standard question on an early dinner date would be; "And how are you crazy?"
The problem is that before marriage, we rarely delve into our complexities. Whenever casual relationships threaten to reveal our flaws, we blame our partners and call it a day. As for our friends, they don't care enough to do the hard work of enlightening us. One of the privileges of being on our own is therefore the sincere impression that we are really quite easy to live with.
We make mistakes, too, because are so lonely. No one can be in an optimal state of mind to choose a partner when remaining single feels unbearable. We have to be wholly at peace with the prospect of many years of solitude in order to be appropriately picky; otherwise, we risk loving no longer being single rather more than we love the partner who spared us that fate.
Choosing whom to commit ourselves to is merely a case of identifying which particular variety of suffering we would most like to sacrifice ourselves for.
The person who is best suited to us is not the person who shares our every taste (he or she doesn't exist), but the person who can negotiate differences in taste intelligently - the person who is good at disagreement. Rather than some notional idea of perfect complementarity, it is the capacity to tolerate differences with generosity that is the true marker of the "not overly wrong" person. Compatibility is an achievement of love; it must not be its precondition.
Romanticism has been unhelpful to us; it is a harsh philosophy. It has made a lot of what we go through in marriage seem exceptional and appalling. We end up lonely and convinced that our union, with its imperfections, is not "normal." We should learn to accommodate ourselves to "wrongness", striving always to adopt a more forgiving, humorous and kindly perspective on its multiple examples in ourselves and our partners."
