My ASD husband did.
He ran back and forth across 6 lane highway. It was middle Sunday morning, and people were coming back from church. I was so angry and upset, I almost did the f**k him, let him die. But then I thought what if he takes someone's grandma out in the process? Could live with that? So I called the police.
Six squad car showed up, and by that time he was trying to get into his car to *get away*. The police blocked the entrance, and blah blah he was taken to the ER.
Medical floor, then psych floor for two weeks.
That was the start of his journey for his ASD diagnosis. He got his diagnosis about 9 months later.
We know he did that in during a huge meltdow, and he says he doesn't remember anything after he started runnning towards the highway. I told him, if he EVER pull that again, I'm gone. Like next day moving van and filing divorce papers gone.
The first time, I gave it a pass. The next time, it's a self indulgent, BS act. And I don't play games. We can figure put how to deescalate the meltdowns before they get that bad. I can work on learn to talk/act during those situations so my husband doesn't use that as the default to go escape action.
He has a therapist and a psychiatrist. Use their brains to figure out how to avoid/cope.
My husband was 50 when he did this, so he wasn't a 10 year old child. You are 31. Do you know will be left of you if a car hits you at 45 mph on a busy road with three more cars driving over your body because they couldn't stop? Or if you get someone else killed because he was trying to avoid you?
Or just alive enough to get tortured in ICU, then winding up a nursing home maybe permanently?
Physics doesn't care about your lack of coping skills or suicidal ideation. F=mv. You can't joke away the force of a car hitting a human body.
I feel very sorry for you if that is your default coping skill. And even worse for the people who have to see it before, during and after. It is not fair to you because that is no way to live. It took me a good three years to trust my husband after he ran. It is the equivalent of point a gun to your head in front of everyone, and screaming, "I'm upset." The people watching don't know if you have one bullet, six bullets, today is a really good day to die or I'm doing this (not pulling the trigger) for attention.
From this end, my husband might as well had a gun. At least he would only potentially hurting himself or me. Running around a six lane, busy highway put people's lives endanger that had nothing to do him. That is totally unfair.
If this sounds harsh, truth is truth. You not coping can get yourself or someone else killed, who had nothing to do with your unhappiness.
*It is one thing when a LF, non verbal child takes off running. My husband he decided to run across the road knowing it was busy. I don't know if your situation is like the child's or my husband's. Either way, someone and/or yourself needs to come up with a better plan.
