After approximately 8 months, it has happened. Today.
Before I continue, I am not after sympathy, nor do I intend to bad-mouth the other person. I'm also not after advice.
It's a sad fact of life that when you get two people with autism, no matter how hard they might try, they always seem to misunderstand each other and end up getting stuck in a negative feedback loop that just cannot be resolved. When that happens, the kindest thing we can do for ourselves and the other person is to walk away, be thankful for any good times that were shared, and then take time to heal.
