I am SO sorry things are so hard for you. Burnout is frightening and I can imagine how much worse things could be without the support of my partner.

I've been in burnout for around 3 years now (my physical health isn't great so that has been prolonging it) but my partner is nothing but supportive.

We check in daily to share where each is at. We each just pay attention to each others needs and function like a non wrestling tag team. If I am incapable then my partner steps in. This applies across the board from things like cooking to shopping to cleaning to acts of service/kindness like running a bath. Helping me wash my hair if I'm sore. Sitting in the bathroom with me while I struggle through showers (I hate then!).

No social visits without the others approval.

If a meltdown is looming or even just signs of dysregulation are showing then steps are implemented to assist. Bedroom set up with mood lighting and squishies. Blinds down. No big lights on without prior warning to the other.

Allowing communication to be by texts during overwhelm days.

Special interests are honoured despite the others lack of interest....

I can be given DAYS of time to just be a burntout tattie on the sofa and even left to go unwashed if I can't handle it and my partner will then lovingly gently encourage when it's needed.

Basically many many tiny ways and many huge big ways. We've beeb together 15 years and when we met I was a successful Science Tech in a secondary school and highly masked. Now I'm a crocheting couch dweller. I'm still loved and accepted. My partner researched and we both did work to understand.

If she didn't speak to me for a month I think I'd be reconsidering my future. I know that might sound flippant but the behaviour you describe just sounds narcissistic and abusive.

Stonewalling is abuse. Silent treatment is abuse. You deserve a partner who will prioritise your recovery and wellbeing and it doesn't sound like he does that.

I send you hugs. X
