Your current events resonate with me. My husband has been going through this crisis for 8 years now. He left for a month back in 2012 right after BD. He returned and then went through major withdrawn/depression. He was home, but not really home. He actually set up our shed as a make shift suite and stayed in there for 2 months. He then had some clarity and came back into our home. For years he cycled through depression and slight withdrawal after. However, he was almost back to himself but you could see the depression hidden beneath the surface. This past year I thought maybe it was finally over just to find out, nope. Major BD and gone again. Left for 6 weeks a text a few times a week, came back, moved to our commercial property and has been staying there since. I am praying it is a case of going through it all again to close the doors and face fears. For me it is the uncertainty that is unbearable. My heart breaks for you and your daughter, it is so hard on the kids.
