I am absolutely not going to defend him, but I am going to pose a different perspective.
I don't think there's a definition of "love" that works for a lifetime. That lusting "love" of an early relationship is chemistry. Its science. Its evolution. It's actually the very carnal "survival of the species" stuff. And lasts, according to science, for up to two years - and often less.
The idea of lifelong marriage was a relatively recent idea (that not all humans have ever subscribed to) and worked fantastically when at least one person - usually the woman - was dead at an early age.
So love is so many things, has so many forms, that I don't think being unsure about if you are in love or what that means is a simple equation. Or one that doesn't change. Or even be confusing as hell...
So the question isn't really does he love you, or even do you love him, but can you NOW find common ground about what you can share that enables your relationship? For some people fidelity is not the measure, for others it is. For some people the housework is make or break. For some "friends with benefits" is great. All these and more are "love".
People here will have their own opinions. But those are what they call love - that's not the same thing as you call it, I call it, or your husband calls it. You need to decide what you can live with, or without... and not what we want!
