@johnnxiv,
It takes a while for breakups to heal. You can't expect to feel all better in just one week.
Understand that you did what you could. Now, learn from the experience. You don't need to be in someone's face all the time, but this particular woman thought you were inattentive. So recognize that that might be an issue (but also keep in mind that this is a balancing act, like many things are, and not everyone likes the same levels of contact and connection).
My experience has been that it's usually a bad idea to go after someone after a breakup. It is not impossible to reconcile, but the power dynamic tends to change, and often not for the best for either party.
So be broken up, and mourn your lost relationship a bit, but try not to wallow in that. Spend time by yourself, or with friends, or doing good things. Surely there were people in your life who you saw less of when you were dating this gal, so make sure to reconnect with them. And the time will pass, and you will get up one day and you'll feel better.
