sorry about the emotionally draining couple of days. I admire you for your calm demeanor and willingness to listen to your W.
It sounds like she is in a deep depression. I'm not sure what kind of effect letting a person who is deeply depressed hit rock bottom could have. I feel like maybe she does need someone stable to hang onto as she's struggling with this. Would being on her own make her drown? Will she be able to make it? Would it push her further into depression?
You've done an amazing job being there for her for a year, and I can't imagine how drained you must feel.
It sounds like she wants to run away from all the problems. She feels guilty, and even though she hasn't shown much attention to your S's, she must feel guilt deep inside. Does she have any interaction with them? Does she initiate any interaction with them? Maybe her guilt in letting everyone down makes her think that she's not wanted there anymore.
You have a lot to think about and think of possible other approaches. Just remember that it is not your job to fix her. She needs to figure this out herself, but it sounds like she does need your guidance in some way.
I agree with BF that it is good that she's reaching out to you with her talks. She's struggling and she needs help. It's feels so horrible to watch a loved one suffer like that and not being able to do anything about it. You are doing the right things by taking care of yourself and your sons. Everything will be alright one way or another. You'll get through this. ((rick))
