Don't know if everyone else advised this yet, but you have got to quit with the pursuing her. No more flowers. No more lame excuses to talk to her. If you want any chance of getting her back it's going to have to be because you are such a catch...not because you chased and chased (actually "chased" is the correct term...you'll chase her away if you keep sending notes and flowers).
Counter-intuitively, just because you didn't show love to her in the way she wanted, doesn't mean that now you show her and tell her. She doesn't want to hear it. Everytime you consider doing those things, think to yourself "she won't see it as loving...she see me as pathetic" and you'll avoid some of those pitfalls.
So, what can you do? You can focus on being the best you that your capable of being. You can be friendly, if you talk, but keep it short. Listen if she wants to talk, but don't initiate conversation yourself unless it's something short and sweet, like "how are you doing?" In the meantime, focus on trying to get your own life in order as though it won't work out. I'm not saying it won't, but you do need to have a complete life of your own, even if your wife comes back. She'll choose to come back to a man that has his act together, is strong, confident, and respects the fact that she feels it's over (for now). Quit with the clingy stuff.
