Lesson for next time:
Never park where he can block you in. NEVER.
Walking 10 minutes to your car is nothing compared to this:
45 mins of entertainment for the neighbours as I beg him to move the car as I have promised myself to leave each time he gets abusive. He's hitting car and calling me all sorts of names.
Alternative: Blocking your access to leave generally qualifies as domestic violence legally. You can tell him that if he doesn't move his car immediately you will call the police. But only say this if you have confirmed your legal status... .and are willing to do it.
