Read part 61 for the requirements. Basically you'll need 250 hours for the CPL, so you've got 28 hours left to fly and you'll easily get everything done in that time. You can get a 61.75 certificate (piggyback/on the basis of) which will give you PPL/IR/MEP privileges. Then you'll need to fly the necessary theory, IR and CPL tests. The theory is very straightforward, you'll need about a week to study. The practical tests are harder as they include an oral exam and ground reference/performance maneuvers which you won't be familiar with. Career-wise I'd recommend getting a CFI rating and using that to build flight time. Since you have an EASA fATPL I'd recommend trying to keep your EASA licence valid pending the divorce.
