Well tbh.

There's nothing that can change now. What's done is done.

If you truly love Adam, just be the best for him and care for him in those daylight hours. I'd say your situation is very unique so the cheating, while bad, is somewhat understandable.

Don't forget he worked extremely hard and provided for you and your family for all those years. You owe him this time in the sanctity of marriage to return the favour. Though the whole feeling of rape what a bit over the top. This guy is still Adam, it's still your husband. What's happened to him is a tragic tail.

Did you support him after he lost his job? Did you help him look for positions? Did you offer a caring side? He took a huge turn for the worst which may have been prevented if you weren't selfish and truly cared about him.

If you're gonna cheat on him, fine. I don't think he will be happier in any other situation so unfortunately it sounds like he's stuck with you. Just don't leave him and make his life even more a misery and don't be a massive cunt to him when he's awake. Try to find the good in the situation and seek happiness.
