Sherril, I am so sorry. Here are a few thoughts...
It's sad because I hate to see his whole life ruined.
Last time my son was in jail for a period of time (he got out in June 2014), he was facing four years in prison due to his violating probation (the probation was on two felonies). He had a public defender. He told me later that the night before he went to court (we had long since stopped going to court and paying for lawyers and providing bail so we weren't there and not a part of any of this), the public defender sat him down and said this: You are going to jail for four years tomorrow. Get ready.
My son said he laid awake all night long, terrified. The next day they went into court and not only did he not get four years, they let him go that very day, albeit with lots of fines and more probation.
Since that time, he has steadily progressed in rebuilding his life.
My point is this: We cannot know the journey that they need to take and are going to take. It is **their** journey, their own, individual journey, not our journey.
My son's whole life has not been ruined by his record. I used to think that was the case too, but my son is on a path to becoming a journeyman electrician now and doors are opening. He is making them open, not me.
Sherril, you and I cannot fathom homelessness, drug addiction, jail, prison, buying and selling and taking drugs, all of it. We can't even begin to grasp it.
But that is the path our own precious children have gone down, and okay...then so be it. It is what it is. People do what they do. And then they have to accept the consequences.
I am in no way saying that the above makes your decision for you. It doesn't. It is your decision, and yours only.
We had to stop bailing my son out of jail and paying for lawyers a long long time before this. I think we paid for a lawyer the first two times. (he had 8 or 9 go-arounds). The reason we **had** to stop is not due to financial reasons. We could have paid it. It was due to realizing and believing that bailing him out didn't help him.
Helping didn't help.
What does your "gut" tell you to do? Will you resent paying for this, or can you absolutely **not** not pay for it, in other words, you can't conceive of not trying this to help him?
It is about whatever you are ready to do or not do. You are on your own journey and we can't know what path you need to take either. Maybe the path is to pay for it. Maybe it isn't.
Either way, it's likely not a do or die decision, even though it feels like one.
You have gotten good advice and good thinking from these responses. Please let us know how we can help you further on this, and anything else.
Warm hugs today. This is the hardest stuff in the entire world.
