I hope you feel less alone after these posts. Your situation and mine have a lot of similarities, from meeting in high school to buying a house a year before BD (and what the heck to do with it??) to H saying there's no chemistry/compatibility (oh, and our screennames both start with K!) I've been in Newcomers because it didn't make sense to post in MLC when my H is only 28... but as another poster said, the crisis can really happen at any time. I'll keep an eye on your thread!
