He is defeated.. for now..
At this point he has his small group of "peasants" who were just learning how to fight vs. Negan and his army.
At some point you have to realize you don't have the numbers and bend.. Michonne brought up Hilltop last night.. With her finding the Mattresses burning it will "light a fire" under her and Rick to find a way out..
Cue up Carol and Morgan at some point showing back up at Alexandria to talk to Rick about The King.. Once that happens, then Rick will realize between The Kingdom, Hilltop and Alexandria they might have a fighting chance..
Until then your job is to keep your people alive, even if that means

to Negan for now.
