I understand how you feel. I have been playing for nearly 50 years now and I find it funny the way "the business" changes from one generation to the next. Hell, used to be that when a "band" started up - there were no "side projects" for anyone - in other words, once in, you stayed "faithful" for the duration of the band. I honestly think that it was supportive of the work ethic in those days. You know - "we built this ship and come hell or high water, we will float or drown together". That sort of thing.
But like everything else - times change. Today? musicians flitter about (myself included) from one "job" (and I use that term VERY loosely) to another. Hell, a friend of mine is currently in 6 different bands. How the hell he can keep it straight from one gig to another, is beyond me.
Another friend of mine is fond of telling anyone who will listen that "Free agency killed the NFL" and, in all honesty, he has a point. Allegiance is all but dead in both Sports AND in music. Hell in most facets of life. And frankly, I believe that we have all lost a little something as a result. Damned shame, but welcome to the 21st century.
Not giving advice here - just stating the idea that I know how you feel.
