Bttrfly's advice is so spot on. But, it's also so very hard to really do with the live-in MLCer, I think. As much as I detached, I think I was still peeking peripherally at my ex through laced fingers.
It's so important for us to learn who we are separate from our spouses- from rediscovering old music to discovering new interests. There's not a thing you can do for her so shine that lens on yourself and your kids. Invest in yourself. You'll be happy with the returns.
