I have always been fundamentally baffled about this fact, as a male currently in his mid-30s who never managed to attract any female.
If this had happened, and we had got so far as to get married, and have kids, that would automatically mean that we had some kind of proven compatibility. Very few things could possibly upset that later.
My only guess is also a very strong suspicion: they must be absolutely lying to each other from the first meeting up until when they realize that they aren't actually compatible at all. That's the only reasonable explanation.
This whole thing about "drifting apart" sounds like utter nonsense to me. What does that even mean? "Drift apart"? Either you are compatible or you aren't. It seems very clear to me that they (or at least one of them) weren't honest about who they were, or it would not have happened.
And, of course, this is one major reason why I'm miserably lonely: I simply don't "have it in me" to put on such a fake facade. I just cannot. It's just as bizarre to me that all these people are able to lie like that as it is for those people to understand how I can be this "honest". I don't even consider it honesty, but rather... "basic non-deceitfulness".
It seems like an even worse crime to pretend to be somebody else and waste somebody's life and emotions than it is to rob them of a large sum of money or valuables. It seems like it should be illegal, as long as there are going to be laws about all kinds of things anyway. I guess the problem with that is that it would be very difficult to prove in court who lied about what.
I consider it to be extremely evil and disturbing behaviour to put on an act in order to trick somebody to become attracted to this persona that you act as, but frankly, it doesn't matter what I think about it -- I couldn't do it no matter how badly I wanted. I've tried, because I certainly have the same urge (if not even more intense) as "normal males", and it's clear that the real me could never get me in any kind of relationship.
But I just can't do it. I guess I have what must be considered an illness in this world?
