So, let me get this straight... You already spent a grand on her...and now you're looking at getting your own place just to please her... OP, please tell me you're joking.
Let's say here, for example, you get your own place- a nice one given what you can afford. Now, in this hypothetical situation, that's great and all but that doesn't mean that she'll love you back suddenly or want you. You have to remember that you can't make someone love you back, so you need to start living your life for you. If you're happiest living at home and waiting to buy a house, live at home and wait to buy a house. Any woman that actually cares about you would understand when you explain the situation to them. Who knows? Maybe there's another woman out there who is trying to do the exact same thing.
Either way, I don't think this situation with the stripper sounds healthy at all. I think it's best if you move on. Life is too short for you to spend it attempting to please others and make them love you.
