Of course the ex - who showed up with a friend, or another thug, depends on your point of view - didn't believe that she wasn't home. (Liars never believe a truth that doesn't meet with their approval.) So the ex and the thug try to force their way into the house.
The two men tried to enter the home and fought with the boyfriend before shots were fired.The two goof-balls are charged with assault.
The two men were hit and fled to a nearby home where they were apprehended and taken to John Peter Smith Hospital.
Self-defense may be a human right, but the "authorities" in this case are still investigating, since they really want to charge the current boyfriend with something.
