As with a lot of things in life, I think a part of the problem is perception. The OP may consider herself to be "not bossy" and "very funny" but if the PA guy perceives her as bossy and unfunny, then in his mind and in his reality this is what she is.
I will say, OP, that in this particular thread you seem more defensive than in other threads I have read. This is my perception, based on your reactions to specific comments. Judging from other threads, I assume this is because this particular band means a lot to you, and it hurts all the more to potentially have to leave it (in some form or other).
I've had my share of P/A and conflicting personalities in my life, so all I can offer is: best of luck and I hope it works out for the best. Cos every situation is specific and there is no "one size fits all" solution (although I do adhere to the belief that direct confrontation will lead nowhere, with P/A) people.
