You can't assault someone because they "harassed" you.

This appears to be a marriage question, not a legal question.

This is not a legal issue...............................

Basic rule is your employer can terminate you for any or no reason, and you can quit for any or no reason. Exceptions are in the answer above.

You can sue for millions. How much you recover, if any, depends on the facts of the case.

IMO you can refuse. IMO they can terminate you for doing so. Others may disagree.

Have someone drive you there, and return the car. If Jeep won't pay for the balance, consider small claims court.

Given that this has already happened, there is really nothing to do at this point.

It is too late to sue..............................

You don't indicate who you would sue. Not clear you have a suit against anyone.
