As you know, your landlord can sue you for the unpaid rents due for for the remainder of the lease.
Your landlord can recover damages but must also "mitigate his damges" by attempting to re-lease the property to another renter. Here, you report the property was rented out two months after you moved out. The landlord's damages are the difference between what you owed on the remainder of the lease and what the landlord was able to recover by renting. If the landlord rented for a lower amount than was due under your lease, you would owe the difference between that amount and the amount you agreed to pay. If the landlord was able to increase the rent, then he may not have incurred any damages and you might owe nothing.
If there is a judgment against you, then the landlord can enforce the judgment when you return. Under some circumstances, the landlord can enforce the judgment by levying on your wife' bank account. There is not enough information to answer that question. You can find out the status of the lawsuit by checking with the clerk of court wher the case was filed. Some courts have these records online.
