So, I have been in this band for 2 years, we have done many rehearsals no live gigs, not a single one, only live Facebook shows, I don’t do music full time, but I like it. However, things have changed since the corona virus thing, my country is under lockdown and I am not getting paid by my regular job, because I can’t work due to the lockdown. One member of this band is a pop artist and she has big plans, I can’t tell if something will come of it or not since there are no gigs. The problem I have is that every time we rehearse to do one of these live shows, she asks me to contribute a large amount of money so that we can party after the show or she wants us to rehearse over a weekend and stay over so that the money can be said to cover our living expenses for the weekend, the thing is at the moment I can’t do this because I don’t have money, furthermore, I don’t get a say in how songs should be done, I am basically just doing it because I love music. I am thinking of quitting should I quit?
I'm going to add this an an answer because I think you deserve it in letters bold & large.
Someone is taking you for a ride. They're extracting everything they can from you & offering absolutely nothing in return.
This isn't a band, this is one person's perceived free ride to fame - which they are about 0.1% likely to ever achieve even if they're actually very good.
You have one member who thinks that in order to become a pop star, you first have to live like one. They are so self-centred that they expect others to pay for this…
This is, to put it bluntly, arse about face.
This is not behaviour that a quick band chat after rehearsal is ever going to fix, this is simply delusional behaviour.
Leave, leave now.
Don't look back.
Don't apologise, just go, now.
