My wife never really moved on after our only son passed away. She's had counseling, medication, and one involuntary stint in the hospital, but it seems that she's still pushing everyone away, me included. After conferring with her friends, most of whom can't bear to be around her anymore, it's evident that she's under the delusion that someone giving us their child (as we cannot have any more of our own) would magically fix it. I think it is an attempt to get a "do over" with our son, and I wouldn't really be comfortable with her and children right now.
None of us are sure what to do, and there's a common consensus that she's pushing everyone aside so she can feel free to either waste away or commit suicide. I'm calling her doctor on Monday and relaying all of this, but what gets to me is more the contempt she has for me and everyone else. It's really hard to deal with.
Pray that God illuminates the path for us. We love her, but we can't help her this time. Nobody can but God.
