If your boyfriend did not have permission to drive the car, then you cannot be liable for its use. However, if he reasonably thought that he had your permission (e.g., if you had let him drive it with some regularity before, and if you left the keys in a location where he could access them, without any effort on your part to secure them), then it would be regarded as a permissive use. You may obtain indemnity from the boyfriend for any damages you are required to pay, but if it was a permissive use situation, you would not be able to avoid liability.
