I think love, like nearly everything that goes on inside a human head / heart in a social setting, is a bit of a mystery. Materialists will reduce love to chemical reactions in the brain and they are certainly correct insofar as that goes. But while it is correct to say "my house is fiberglass assembled in a certain configuration" (I live on a boat) that doesn't really mean the same as "this boat is my home".
In a like manor, it may be correct to insist that my relationship with my wife is a mixture of the chemical reactions in our brains that we invoke in each other, but that doesn't really mean the same thing as "I love her".
What any of this has to do with not having a god belief is beyond me. Even a cursory glace suggests that religious people are not any better at loving than are others. Indeed, one could make the argument that the more religious a person is, the more likely it is that they will be judgmental, violent, heartless and cruel; hardly characteristics of those who have learned much about love.
