P. S. The reason as Rob said that “similarity is not sufficient “ is that yes, similarity is necessary in common beliefs/values, maturity level, IQ (I know, politically incorrect but true), and “life’s goals” aligning or at least cooperating.
HOWEVER, the other part necessary is OPPOSITE PERSONALITY STYLES (for which I have developed a system very different from the Big 5, not data based but theory based) called the Social Personality System in which OPPOSITES ATTRACT (like the elderly couples in the old film, When Harry Met Sally).
The truth supported by research, literature such as Shakespeare, well-loved film and tv such as version I of Sex and the City (not version II), Entourage, the film by Mike Nichols, Closer, and numerous others, and supports by even Aristotle in Nichomachean Ethics tell us that love that lasts is BOTH LIKE ATTRACTS LIKE and OPPOSITES ATTRACT. (“Like” in “content” and “opposite” in “style” of communication and behavior, which is what personality is.)
Example: two democrat Buddhists with one a King style (phlegmatic) university professor and one a Magician female (sanguine)chief of sales for a car sales company.
Or
Two republican Christians with one a Lover style (melancholic) male poet and the other a Warrior style (choleric) female attorney.

That is lasting love.
