So, I have this client/ friendly acquaintance / borderline friend that, for the past two months, has been trying to schedule a dinner between six or eight people (all busy professionals).  Understandably, it's difficult trying to coordinate the schedules of a bunch of busy people, but I feel like I've reached my wit's end with the bi-weekly string of text messages and emails with new proposed dates because someone can't make it, or a restaurant is booked, or whatever.  It's gotten to the point that she's throwing around dates in March and April, and this coordination has been going on since October.

I really just want to be able to say "No, I'm not interested in having dinner with you at an expensive restaurant an hour from my home on a date certain two months from now."  But I can't because we send each other business somewhat regularly, and we've done work for each other's businesses too.

I'm getting pretty annoyed by now because (1) I have no idea what I'm going to be doing in two months.  There are millions of things that could come up that would take priority over a friendly/professional/networking dinner.  (2)  She keeps suggesting high end restaurants that I really have no interest in going to.  Sure, we can all afford it, but I really have no interest in paying $150+ for me and my wife to put on a tie and drive an hour to sit uncomfortably at a white table cloth dinner with a waiter that comes around with a crumb scraper.  (3)  I have no idea if I'm going to be paying for myself, if the bill is going to be split between all of us, or if her business is paying for it.  I definitely don't want to sign up for splitting a massive bill with some of the other boozy invitees.  (4)  I would be much more inclined to attend if she said "I'm having a BBQ at my house on this date, a bunch of people are invited, come if you can make it!"  I just don't feel right making a commitment two months out, and I don't want to feel like I'm obligated to go to this thing if she keeps moving around the schedule to make sure I'm free on that date.  (5)  If she wants to be friends, let's be friends and do friend stuff.  If she wants to do professional networking, set up something professional.  But I can't stand this constant blurred line between the professional and personal relationship that she's trying to ride.

Am I the asshole for not wanting to commit to a dinner with someone who sends me business?  Is she the asshole for expecting commitment so far out?
