I know im kinda new to the website, but my situation has been going on for a while.

Its sounds like you haven't detached enough from the situation. If your talking about the M, your saying to much imho. I know for me, and it took a while, but the GAL was a huge deal for me.
Maybe this is bad advice, but if you want to save your marriage, then you need to risk losing it. Your chasing still, and at least in my case, that seemed to make it worse.

It wasn't until she noticed I could have a life without her, that she started to come back and wonder.

I hope my advice isn't too off base, and look forward to some of the more vet follow up posts.
