When you said earlier this thread is getting crazy was that a warning for this?
Because this together with some of your other updates are the craziest things on this thread.
You say he’s intelligent so he is feigning ignorance and incompetence here. If he kept having similar accidents at work and hurting others or even damaging property and his boss sat him down, you think he wouldn’t come up with a better solution than “not using doors”? Of course he would!
While I’m not necessarily saying it’s deliberate - as in going out his way to purposefully jam his child’s fingers, I think the sad truth is he just doesn’t sufficiently care enough to pay more attention which you actually admitted in the initial post.
He knows he’s “accident prone” as you describe it, but yet isn’t doing all he can to ensure his tiny child isn’t harmed further.
I think the therapy you suggested is probably more useful than trying to get diagnosed with any ND in the first instance which can be a long process . Because then you can talk about how this makes you feel and how this impacts your marriage. Of course you can do that without a therapist too but given how he responds it might be helpful to have a third person.
I wasn’t diagnosed until my early 30s, but I already had strategies in place my whole life really. You don’t need a diagnosis to implement strategies and to show concern for those around you.
For example even pre-diagnosis I knew I had an issue with being on time, so I plan to leave my house an hour before I need to meet someone. Inevitably that hour turns into leaving just ten minutes early or on time - but if I’d planned to leave on time from the start , I’d end up leaving an hour late. It’s just little things like that to show consideration for the person waiting for you.
The fact is he should be the one raising this as an issue and being proactive on finding solutions to this problem. He should be showing how much he wants this to stop through his actions. Again his lack of apparent concern and drive to address this isn’t a ND thing.
