What constitutes a basis to love someone romantically?

In order to be in love with someone, do you need to share the same values? The same mindset, general principles, and/or goals? Should you share a need for intellectual curiosity and stimulation? What if some of these conditions are at odds with one another? What if you’re inherently different people? Does this mean you cannot love him/her? Can a conflict of the minds mean you cannot be in love? What if one’s view of the world, way of thinking, questioning, and exploration stand in stark contrast to one’s more simple and less educated nature? Are they incompatible as lovers? How much should education and intellect really matter?
