Annddd....chiming in cuz H was in the same place. He is coming out, but still has a ways to go.
Is it normal to feel that way? No, but asking your wife won't cause an epiphany. Sadly, this is not something you can really help with.
A friend of mine has suffered from depression for years. His wife just told him she is done. That caused him to seek help. So I think that unless you find something more to lose than yourself it's a really long road.
