Seriously, regardless of where your emotions lie with Tali, or your fondness of the Geth, I think it should be clear that the best option for both of them at this point (or sometime very, very soon) is to just suck it up and make peace.
If we learned anything from Legion, then the geth are at least willing to consider peace. And unless the Quarian scout fleets sent out to find a new world in uncharted territories come back very soon with really damn good news, the Quarians don't have a better choice for the survival of their species than to make peace with the geth and try to work out a deal for their settlement of a new homeworld.
They are obviously going to need Shepard to guide them one way or the other though, because some of the Quarians have their heads shoved too far up their asses to see what is best for everyone in the long run. That, and they lack the knowledge Shepard has of various key factors, the Reapers being one of them.
