None of those tricky details makes much of a difference, you still need to break the lease. Let your landlord know ASAP and ask them to begin looking for a new tenant (as should you). Be prepared to deliver the property back to them in pristine condition, and then get on a payment plan for repayment of the fees associated with breaking the lease.

Then find a cheap room rental close to work and start to recover financially.

In the mean time, close any joint accounts with your wife (sounds like they are empty) and make sure that you remove her as an authorized individual on any of your personal credit accounts.
