Evio,
I am three years out from one DDay, and two years out from full disclosure.
The feelings you have are normal. You aren’t feeling the way you are because of autism, nor because of ADHD - but because of betrayal trauma.
You are experiencing NORMAL EMOTIONAL RESPONSES to a very real life situation.
Think of it like this: if you had a severe leg injury, you would experience pain, swelling, doctor visits, Xray, possibly surgery, a cast, difficulty walking, and scarring.
Would you expect to go for a ten mile hike right away? No. Jump on a trampoline the next month? No. Run a marathon, do kickboxing, or play Twister? No, not right away.
Those are NORMAL after an injury, and you might wonder "will my leg ever be the same again?"
Fact is, no, your leg will never be the same again. BUT YOUR LEG WILL HEAL, and will be "better" than the day you injured it.
So in this case, you have had your emotional soul injured. The pain, sense of loss, change in how you think about your relationship, all of that is fallout after the injury. Over time, it lessens.
But you will always have this scar. Whether or not you stay married, the scar will remain.
Recovery is the process of healing the pain and damage. It doesn’t mean you forget it, it doesn’t mean it all "goes away" once you’re more healed and working on reconciliation (or even working on making a new life separately). Like the leg injury, the scar remains, and on cold days you may even feel pain where that injury happened.
Over time, the pain lessens, and your ability to deal with the evolving emotions improves. The waves of sadness slow in frequency and intensity. And you may begin to see your feelings towards your WP improve (or not). But time helps you make better decisions.
If you decide down the line that you want to leave, know that there are no rules that say you waited too long. That’s not how it works. Marriages only work when both people want to stay in the marriage - and any time one or the other decides they do not want to be married anymore, they have the right to file divorce.
