She left you because you were a jerk. Now, you're looking for ways how to get your ex girlfriend back fast. You want to rekindle the love, care and attention she used to feel towards you. I bet getting back together with you is the last thing on her mind. However, this does not necessarily mean that your break up is going to last forever.

If you're willing to work on it to win your girlfriend back, here's your TO-Do list:

1. If you have done something terribly wrong and want to ask for forgiveness, let her anger simmer for awhile before showing your face in front of her door. If you want to get your lady back after you cheated on her then a personal apology may take a while.

But you should not be afraid to call or text her. Let her know you admit your mistakes and you think about her all the time. Let her know where you are, what you're doing, how your day was and that your day would have been complete if she was with you. Do one simple "nothing", a gesture, everyday until the air is clear for you to show up personally.

2. Apologize to her personally. Treat her with care and respect that she deserves. Part of learning how to get her heart back means finding the time to make her feel like she is the only woman you'll ever need and want. She is your princess. Remember, the most important things to her, anniversaries, special events, and memories in her life.

3. Although she may already be willing to see you again, it doesn't mean that you can continue where you left off. She may need more time. Give it to her. Don't push it. Let her know that you are willing to wait for her. Stay in touch by sending her casual messages. Don't overwhelm her if she wants to think things through. Keep everything light and easy going.

4. Be good. Stay away from the ladies if you want her to forgive you and forget what happened. You want to win your ex girlfriend back because you know that she's worth a lifetime of your happiness, right? So let me make it clear. Change.

5. Ask her out when she's ready. You can start by just going for a coffee. This will show her that you are sincere with your word that you're waiting and you don't want to pressure her. This will allow you to subtlety let your ex girlfriend know that you truly want and deserve a second chance. To get back with your girlfriend you must be willing to go the extra mile and make sincere sacrifices to save your relationship.
