Nobody can truely know your sitch except you and W. A lot of people (and ALL my family) still think that H and I are 'ex's' - well, if you and your W get back together you will have the satisfaction of proving everyone wrong.
Re your W's depression and possible hurting of your son, I don't think she'd do that. Even when I was suicidal, I never laid a finger on my kids and never would. Mothering instinct goes beyond depression in most cases unless the person is psychotic or something.
It's good you can parent your child together after just 5 months of separation, that's something to build on.
