I'm probably heading for divorce... I feel so empty

There is a chance it won't happen, but most likely will. I feel like I lost my confidant, my one safe space. And I cry every time I think about the days I wouldn't see my kids. If it happens we agreed to 50/50, but I've never gone without my kids for more than a night. She said she doesn't know what she wants, that she still loves me, but I feel like I lost my best friend. And I'm worried my kids will drift away from me. I could lose everything.

Logically I know things should work out, but it sure doesn't feel that way.
