There’s a saying about drug addicts that they stop maturing emotionally at the age they started using, and I’ve known enough addicts to believe this to be true enough. I think the same thing can happen in longtime monogamy. Perhaps some of your limited interpretations about what it means to say the word “love” are left over from what you thought it meant all those years ago, when you first committed yourself to your ex-wife. That was the past, as you say, but I suspect that a piece of yourself is still frozen there.
