lool you people crack me up.. whats wrong with a single-mothers or devorced women? If the age isn't an issue for you, then you're probably good to go. Her putting her child ahead of you right now is good sign, shows she knows her priorities.
Plus she's been married so she knows what NOT to do, you won't have to deal with any of the bickering inexperienced girls usually bring. It's a rough market for girls nowadays and having experienced all that time without a husband will probably make her appreciate you that much more.
But you're definitely making this up so none of this really matters
