Coordinating a social event with your friends will require a lot of back and forth today, which isn't surprising. What will be surprising is that someone you usually look to for support is suddenly saying 'no' to all your ideas. They are just generally being quite difficult to work with, too. Instead of trying to overcome their objections, just hand over the planning to them. If they don't like what you are cooking up then let them figure out something better. They'll love the challenge.
