Re: Disappointment in bassists :/
You weren't coming across as anything other than frustrated, so no worries! I'd be frustrated, too.
In fact, all the various bands I've been in over the years have all been frustrating at some point - which is why they all ended in "divorce!" Some bands die more spectacular deaths than others, and like what you're going through, there are always a handful that never really get off the ground. It's always frustrating, but hopefully there are enough good moments to have made it worthwhile and that's what keeps us going.
