My STBXW is a textbook narcissist and the ego hit she took when I was the one to ask for a divorce is apparent in how she immediately went on dating sites and went to a guy's house (I think maybe they're still seeing each other quite a lot) before I'd moved out and lied about it.

Yet she seems to think we're still married in the sense that she asks me for advice on things to help her. For example, she wants to cut her cable bill and she texts me and asks me what to do if she only watches Bachelor and Netflix, etc. It takes all my restraint not to reply with "Why don't you ask your boyfriend?". But ignoring messages like these (there have been many, this is just an example of her wanting me to do her research/work) is the best course of action. It's getting easier.

Anyone else's ex basically acting like you're still married for the good things they can use you for, but then throwing it in your face for the rest (to quote my STBX: "I'm moving on and so should you", which she's said at least 3 times to me)?
