The parallel between your life and my sister’s gave me goosebumps. She also married a hoarder, The trajectory of his hoarding seemed to very much follow what you described your husband’s did, and they also have an autistic son who is obsessed with Pixar! She divorced her husband about 10 years ago now but since they have two kids together his hoarding is still a problem for her, just not so directly. He visits with the kids at my sisters house because his house is too crowded with stuff for socializing — even though he has a decent sized two-bedroom apartment. There are a lot more examples, but I’m guessing you will find out in your own life what it’s like to co-parent with a hoarder ex-husband.
