Well, I talked to the BL and threw all the issues onto the table (except for the It Seems Like You Want To Sleep With Me And I'm Telling You Right Now The Answer Is No thing...). I was direct and to the point without yelling or getting hysterical. I was surprised that the first thing he asked me was, "Is there anything about this that's within my control?" It was kind of a weird way to say, "What do you want me to do about it?"
If your bandleader seemed unwilling to address any of the personal issues, then I think he may be a bit of a lost cause.
"Is there anything about this that's within my control?" reeks of someone who isn't willing to take responsibility for their own behavior. Especially considering his remark about the pill after your gig. I'm in a band with two women, and if a male bandmate spoke to either of them like that I just could not stand for it. It's incredibly uncool.
People skills and personal chemistry count for a lot in a band. Especially if you're in a stage where the project isn't completely about gig income. Someone who feels comfortable behaving like this is probably not a person you're going to want to work with for an extended period of time.
