It's hard, but try to think about how you were when you first met. Full of ambition? In great shape? Paid a lot of attention to her? What?
When you first start dating, you become incredibly efficient at determining what's working to attract the opposite sex. Conversely, when things fall apart, you become totally lost in seeing what works. And some of the changes and things you do will have only a small, incremental effect. You may not see any progress for days and weeks. So don't focus on any signs or portents. They'll drive you nuts.
Pay attention however, to what DOESN'T work, and stop that behaviour ASAP.
