How do I win her back amidst chaos?

Here is the bottom line.....three years ago I met a woman who I feel greater love and admiration for everyday. After two years of friendship, we began dating, and on all levels it was extraordinary. However, over the course of the friendship and relationship my life changed dramatically. My financial situation and occupational life took a dramatic downward turn in late 2007. The stress of this situation pulled at the relationship until the point came when she said she couldn't handle the stress any further. We agreed that if and when I got my own life back together we could explore the prospect of trying again then. However, a year has past, and issues with the IRS, my business partners, and overall financial situation has not improved. She has moved on, we have lost contact entirely, and from my understanding, she is in another relationship and she is happy. I desperately want to reach out to her, tell her I love her more today than I did yesterday and tell her not to count me out yet. However, I made a promise to her and to myself to get my own life straight first. A life without her is not a life to me at all, and without her I feel empty. While I am strong enough to live without her, I don't want to. My life is a mess, she is in another relationship, and I love her enough to want her happy regardless........but I still wake up every morning saddened she isn't next to me. Any suggestions? Thank You in advance for your insight.
