From a girl with depression-
every so often I consider devorsing my husband, running off and leaving him with my 3 kids. other times I can' believe that I even think that. I constantly have the urge to run away when I am down.
The No Past Issue sounds like she has a whopper of a past, like me. I don't bring mine up either. I have let it slip out, but only a little at a time, over the last 10 years, and my husband Still doesn't know 1/4 of it. he never will unless there is a reason.
some questions would be if she went to church before the "fip out"? How long were you married? How long had you known her? Do you have other kids with her or in the home?
You have 3 choices at this point. remain "married" and let her know ( through friends, through the legal system if you have to, or directly to her if you can) that you will be waiting for her to return. make sure that she knows where to retun to and that you will accept her in any condition and will help her get there, if needed. I would even contest the devorce procedings if it's not already finished. I beleve that you can decide to contest at any time.
2nd choice. Allow the devorce to continue. Consider yourself as a person whose spouse has broken a legal agreement and move on SLOWLY.
3rd choice. In some states as a spouse you have the legal right to go get her and seek mental/medical help Against Her Will. She will hate you for it for a while, but she may come arround and love you for it later. She may get grounded and still hate you for it, but she will be stable, and even if she continues to leave it is because she chooses that with a sound mind and not a confused one. That will depend on the laws in your state.
My husband is BiPolor and I am a depressive (possibly BiPolor II) I would make my husband well before letting him make that choice. I would hope he would do the same to me. I would be mad, but in the end I would thank him. (Just like when he tosses me in the shower when I am in a funk. The water is cold and I am mad, but I am out of bed and I get moving and I feel better)
When you cannot stand, on whom do you lean?
