When you think about relationships...any kind of relationship, one thing you will find is that the strongest are the ones where both look at what they have to offer the other, instead of what they can take from the other.
Think of every relationship you have. Typically we have relationships with people where we can use something they have.
How good would your relationship be with your boss, if you didn't use him as an employer? If you don't get that raise you feel you deserve, or you aren't allowed to take that time off you need, is your relationship as good, or is it worse? What are you offering your employer?
What about your bandmates? How good is your relationship with them, really? Is it as good when they make more demands on your time? Is it as good when, they want you to play that lame song you hate? Or do you think of your relationship as, How much can you do for them, and they feel that way in return?
It's no different than being in a relationship like dating or marriage. The worst relationships are the ones where each is thinking about what they can use the other for (sex, money, cooking and cleaning, babysitting, yard work, etc.). Then when they don't get it, the relationship sours. But the ones that are great, and strong, are the ones where each is always thinking..."What can I do for this person in my life?"
Just something to think about.
