I'm voting for no status at all; I'll pencil it in next election if its not on the ballot.
My take on Will is that if he commits then he's all in; therefore, he is cautious about committing (hence why he didn't get carried away when Tony declared his love in Rome). Will knew neither of them were in a place for the big "You're it for me, babe" and laid out a dream situation where he only expected to be Tony's priority when he and Tony have planned meetings. Will, I think could live with Tony being the angsty dorkotronic, but learning that Tony is a serial cheating, lying, selfish, angsty dorkotronic tilts Will's tolerance meter.
Will's a catch; why does he seem to hook up with just about any random D-bag that expresses interest regardless if that interest is even really mutual?
