Are there any magical words that you can use to get back your girlfriend? Of course not, especially if you had dumped her for someone else.
But now that you realize that she is your true love, don't be sad because you can get her back.
Be confident and get back your ex girlfriend, and give her the love she deserves.
In such cases, the first thing that you should do is apologize genuinely.
Don't expect your girlfriend to forgive you on the very first time.
Her heart has been broken; she was rejected for someone else and you were the one to make her go through this.
At the same time, you should be determined in your mission because she is the one you love; and with whom you want to spend the rest of your life.
Give her some, if she really loves you too, she will forgive you.
Establish a friendly relationship with her.
Learn how to control your emotions, for example whenever you see her, greet her casually and move on.
Don't panic or become nervous this behavior will freak her out.
Before you get back your girlfriend, get her back as a friend first.
You need to show her that you have changed and you are no longer the guy who dumped her for someone else.
Maintain a low profile in front of her, and at the same time convince her that she has been the only one that you have loved all your life.
Winning back the trust of someone you have dumped is not easy.
You need to show her that you care and really want her back in your life.
Acknowledge that you were wrong when you ditched her for someone else.
