Divorce because I betrayed her trust - I regret it

[DaB35]

She admits herself she is a prude. She's done this several times, in front of friends too.

She simply wants to not live in the house. I'm not there because she doesn't want me there.

I have been fighting; I keep telling her that we could perhaps just be separated and I work through my therapy and then we try. If a divorce happens after that, I'd at least understand. She even told me in June "I won't make any major decisions until you've got through your therapy." Then she changed her mind. When I picked her up on this she just said "Yeah. That was then. I've changed my mind now."

I am and have been remorseful. I want to help her as I hate seeing her look helpless and struggling.
I understand that she feels neglected and betrayed, and that she says the "whole relationship had an undercurrent of lies." I kept this addiction from her because of shame and I didn't have the bravery to seek help, either professionally or from her/my friends/my family.

She keeps saying how sad the whole situation is. She doesn't want it to happen and "wishes things were different". I want to show her I'm being strong and have a desire to save the marriage. I think she's so adamant that I can't change her mind she just isn't listening.
