Support for people with partners with ADHD

I dont (I think) have ADHD, but my partner is in the process of pursuing a diagnosis.

I was wondering if anyone was aware of any resources that would help me better understand and support them.

I think the strain it can put on relationship is quite well documented, so I would appreciate resource that would help me.

I've tried some podcasts aimied at people with ADHD, and that gives me and insight, but it doesn't help me understand want to do to be more supportive or helpful, as they just tend to moan about things people do wrong.

Anything would be helpful. Cheers all!
