Self work never really stops, it's a continual thing. Whether you're with her, or someone else, you will still need to be in charge of yourself 100% of the time. It might make sense to start the journey without her. You're too bogged down with this chick right now to take an objective assessment of yourself.
You learn a lot about yourself by being completely alone for a while. You learn a lot about your level of need, and your ability to handle silence/solitude, and you're forced to face your inner demons. If you can't handle being alone with yourself, how can you handle being with someone else? Being alone is when some of the best periods of personal growth happen. The level of introspection is unparalleled.
In my periods of being single/alone I've built a business, built a web directory that yields a lot of money each month, built up my condo, learned guitar, traveled, paid off debts, and have learned to keep my life on lockdown. I've made a promise to myself that the only thing that will fvck my life up is death itself. I wonder if these things would have been possible had I been tied down with someone.
Until recently I have avoided LTRs because I wasn't in a place to have one. Now, I can, because I bring a lot to the table, and am in charge of my life. I'll be goddamned if some broad is going to come in and wreck it all. She either adds to my life, or she's gone. The more concrete you and your life are, the easier it will be to separate the women from the girls. You can discern on the fly the women of value from the bottom feeders.
You'll find that as you start working on yourself and on your life, you won't even need to approach women much. They'll come to you. There is something intoxicating (irresistable) to women about the successful man who is comfortable being in his own skin and not giving a fvck one way or the other... because at the end of the day, his life is good. He can do with, or without her. When you reach that place, you're unstoppable.
Quite a rant here, hope it helps.
