Asking your W how her weekend was isn't prying - it's just civillity and politeness. It's the kind of things I ask friends I bump into after a weekend. I think NOT asking those sort of questions is actually sending off a not so good message. You don't have to analyse her answer in great depth and keep on questioning her, but to not ask at all just seems cold.
I would also caution you regarding making threats about actions. You don't sound as though you are ready to do the things that fish mentioned and if you threaten things and DON'T follow through you just lose credibility. Just like with children, you should never say you will do something if you aren't willing to back it up. You will know if you reach that point.
