I don't want to make any assumptions about the loss of license, but I wish you luck with that, bro. I hope you can get where you need to go, do what you need to do.
Is the Jeep the only vehicle in the household?
It sounds like you still want a Jeep in your stable, considering that you're willing to go for an auto while your license is clamped. Will any other Jeep suffice? It sounds like you're pretty open to possibilities at this point with no tremendous attachment to the Jeep.
I'm confident that if you want to keep the Jeep that you already have, the two of you will find a way to make that happen. Reassure your significant other that learning manual comes quickly after a couple sessions in a local parking lot.. You can make it fun... I know you can, if that's what you want. If that's not viable, do you really want to incur the early termination penalty? Check your lease agreement, and like a previous poster said, just do the math. You'll know where you need to go with this. Trust your gut.
