You are a walking ATM, nothing more to her. No matter what she says or how she begs you to stay, the bitter reality is that she has been lying to you from the start and has taken advantage of you.Is it possible to change her? is there a happy ending for us if we keep seeing each other? Why is it so hard for her to get out and to get a real job? I never believe in fairy tales but now I am begging to be in one.
Time to cut your loses and move on. You are not the first, and you will not be the last.
