Wow...
...there are a few things going on here that other's have touched on, so I'll just say that there are many things in your post that make it crystal clear you are, in fact, detached from the reality of what is really going on. That's the only detachment I see at all, and it's not the healthy and loving kind.
"I have not mentioned anything to him cause I am not supposed to be obsessing over what he is doing, which believe me I am not..." Yes, you are.
"...and I am also supposed to be detaching, which I have been." No, you're not.
This entire post describes the behavior of somebody who is obsessing and not detaching.
Please go to Alanon more often, get a sponsor, work the steps, and practice the principals in all your affairs. A lot. It will help you to be a happer person.
