Trying to figure out if marriage is recoverable.

Wife is ex-slut. I got married to her long before exposure to RP practices, thought having an 'experienced' woman was, like, progressive, or something.

Fast forward five years. The other night, we're having a conversation about our sex life. She tells me, "well, I chose you because I was attracted to you but I didn't go dick-crazy for you in a destructive way like I did with previous relationships,". Translation: "I chose you because you were inherently beta-izable."

Is that the right translation?

She did have a history of destructive relationships, which seems to have ended with me. So in a sense, I'm doing my job. I'm keeping her from being an asshole to the rest of the world, it seems. She's actually a very positive influence in many people's lives since our marriage.

Been focusing on getting my shit together for about a year now, some progress. But the question is, even with all this progress, if I've been chosen based on being beta-izable (and clearly exist largely for comfort, to which she is insanely attached), does that even matter? What the hell is going on, what should I do?
