That may very well be true. The fact that for whateverr reason once the authorities got on the scene and when their relationship status was made clear and blows were exchange in the eyes of the blow they had no choice but arrest them for domestic abuse. That may very well change and all charges may be dropped once all of the facts are sorted out.
The charges may become reckless endgerment.
From the poor quality of the video it's diffcult to tell who was trying to save whom.
They will both be charged with something giving the facty they were on the interstate and they could have could a MAJOR pile up.
I can only hope that they both get the assistance that they need. If somone wants to kill themselves, trust no amount of therapy will stop from committing that act.
