Wow, Hurt. I felt like I was reading my own story. The amount of similarities are a bit eerie.
I don't really want to give much advice because to be honest, I don't really know what I'm doing myself. All I can say is this: Give her space, GAL, and take the time to figure out what you need to improve in your life, and what you want from life.
I bought the book 'Holding on to your N.U.T.s' and it's helped me to realize what my boundaries are, and to never waiver form them. The rest can be negotiated, but your boundaries are your boundaries.
If you have time, read my story. As I'm about 6 months ahead of you, maybe you can learn what to do, but probably more what NOT to do.
Good luck bud.
