Newby here, desperate for some advice

[JRuss]

I'm really struggling with detachment. I don't feel like I'm making any progress in that area. My heart still just feels ripped out and thrown in the trash. Does anyone have any advice at all as to how to do this, when you're still living in the same house, still sleeping next to each other, and you're both trying to keep the kids from figuring it out yet? It seems impossible that this will ever be anything other than the worst thing ever.
