Yes, desire difference was probably a part.

I was very busy with evening classes and by the time I got home (my wife worked early) there wasn't really a good opportunity for ML. Combine that with a coworker she had that didn't care she was married.

So, my wife went from mid-drive to extremely HD as part of her affair and a severe MLC. Unaware of this change, I kept low to mid drive during this time. So, the gap widened.

I am more aware, though, of how the *communication* between LD & HD folks is probably more at fault than the ML itself. I think LD & HD spouses need to find a way to better communicate about their needs to narrow the gap. I'm an open frequent communicator but my wife really doesn't not communicate much about personal things. I really wish I knew his more just a few months ago and about the risk that can pose.

So, I think LD & HD spouses can work but takes some extra communication and flexibility to get there.
