Have you talked to your W about maybe having more custody since she likes her freedom so much?
I think part of the reason you are so stuck is because you are projecting a fantasy of this perfect family life and marriage if your W just made a few changes. I would argue you are in a fog right now. You are ignoring reality and that is why you are suffering so much. Your W will most likely take a look behind her some day but I'm not so sure she will see any changes. Just the same nice guy who is a people pleaser and likes to wallow in his misery. What's the status of you getting your own place?
