Naturallyblessed, I am so sorry you are here. This happened to me, Piano, Jstar and is happening to Gatsby and BD (well their H's don't have OWs but walked out on them while pregnant). SO you can find their threads for support as well.
Do you think perhaps oyour H is having an MLC? It can happen at any age...if so, then you might want to ALSO copy and paste your story in the MLC forum and start a thread so the vets there can help you out!
So my advice for now is to just avoid conflict with him right now...was he close to his mom? Is he pretty grief stricken?
