I know this situation oh too well, being a bass player is like being a mum! You do all the work, be the diplomatic one between egotistical guitarists and vocalists who argue constantly over who gets the spotlight like a brother and sister, find shows, book rehearsals, organise everything and 99% of the time it falls apart! My last band finally started to get somewhere with some decent press, tours, management and a label, and then instantly imploded.
My advice, as before, JAZZ! most reliable musicians i've ever met play jazz. Or, if you want to play rock, pick your band mates carefully, if you can find a reliable and non argumentative guitar player, stick with them and keep the core going.
