Particularly in situations where a woman is doubting her feelings, giving her space can do wonders. We're not advocating playing games, or purposely shunning her. We're talking about giving her what's she asked for—space—and letting her figure out if that's what she truly wants. This is incredibly difficult to do if you love someone, but it's the only effective route to take in this particular situation. 

Smothering her at the pivotal point in the breakup, and showering her with over-the-top displays of affection via incessant emails and text messages will not be effective. It will only seal your fate. Keep in mind, she already knows how you feel—now it's time for you to let her figure out how she feels. 

In scenarios where you've made the mistakes, she'll be waiting and watching to see how you'll address them. You should express how you feel, but still use the time apart to work on yourself, and get at the root of the issue. Why did you mistreat her? Are you truly capable of giving her more? Be honest with yourself before you make any effort to reconnect.
