Exhausted & Resentful of ADHD Husband!!!

I'm 57 and my husband is 63...He is hyper, busy, moving all the time, needs very little sleep AND cannot stop talking!!! He has literally no verbal impulse control and over-reacts to everything. I don't know what to do. I want to divorce him, but am leery of starting over---especially financially and as I approach 60. I could care less about finding another partner....I just want peace and rest. I just read Melissa's email message (9/4/24) on resentment and I really do resent the fact that I give more than I get...my pre-frontal cortex is so beat down from having to share it....I so wish my younger self knew what she was getting herself into...I would have run for the hills! We've been married 29 years, and  I feel like a fool. We have a 22 year old daughter and 16 year old son..they are my only treasures/outcomes from this relationship. If I move on, I'd time it to be 2 years (2026) when my son finishes high school and will no longer be a minor. I welcome any advice. I wish there were a divorce checklist with pros and cons already listed for me to use. Thank you.
