If you don't stop rushing in now, then you'll just have to stop it the next time, or the 30th time from now...and there WILL be a next time, unless he's decided to go straight to rehab when he gets out.
It's a do it now or later thing - and most of us have to take a looooong time learning that they are adults and responsible for their own actions, now, most especially their legal troubles.
I started doing so much for my daughter (call attorney, bailing out, listing probation dates, paying fines, keeping track of this or that in case she forgot)...of course she forgot, she didn't have to remember, she had ME.
I felt like the one being punished, and I WAS!!! My money and time and energy were being spent and all she had to do was NOTHING.
