This was such a popular thread I thought I'd fill you in on how it turned out.
I spent waaay too much time this summer riding with riding buddy and less & less time doing anything with family and as anyone could predict the relationship seemed to be heading in the direction my husband feared so I ended it.

Very sad to lose a good friend but it was clear to me at this point that was the happiest alternative.

Of course it would all be for naught if I didn't do something to shore up my home life. My husband is a lot more supportive of my bicycling and much more enthusiastic about joining me for rides. We're spending a lot of time together right now, like we're newlyweds or something.

I hate to say it, but Mr. Silver & others in his camp were right. :P
