Man, you are in a
trio. I can think of at least three trios that broke up because of internal tension or creative control.
It's also pretty obvious that with just a bassist and a singer -that you are the heart of the band. You are both the rhythm section and the lead. Believe it or not -you are standing out to people watching you. Hang in there and when your contract is up -form your own band. Have others audition for you. Then you will be the creative lead and if they complain -you can empathize because of what you are doing now.
In this case -you truly have a case of "That which does not kill me will only make me stronger".
