You don't see how we might wonder how it is she has a 5 year old during your 8 year relationship?
I had (at the very beginning of this thread) a sense tingling of my own, a sense of a certain cluelessness and avoidance, and now this.
I don't want to be mean but I'm wondering if you are a meal ticket. You just casually let her 'have your car' - how many cars do you have (again that sense tingling - how do you get around)? How many expensive trips were you taking her on and spending, day to day?
