No offence with the clip bro. Dan. Pretty funny.
I know you're really upset, but that was a real result, getting the missus to go to marriage counselling. (The people I know who've gone to therapy/counselling have come away with a positive experience). She doesn't seem as hard-core as others might be. I'd take it as a subtle hint that she wants things to work out, at least. (Dubs I know would never go to counselling!)
For now she seems to be on the defensive and acting scared by your apostate views. She might seem a bit extreme at the moment and treating you badly, it's probably a fearful reaction, but I don't think it's because she doesn't love you. Everyone's been a bit 'full-on Dub' at some point in their life. Doesn't mean she can't change. I'm optimistic for you and your family.
