Ok.. Coming from someone that broke all the rules and got my boyfriend back after we broke up...
1st step.. Go out with your friends. Have a good time. Show her that you can live without her. Show her that you have a life separate from her life. Show her that you can trust her decisions (even though may not like it) and that this whole ordeal is a learning experience.
2nd step. If you talk to her.. Don't be whiney. Don't bring up the relationship that fell apart. Don't talk about what could have been or what should have been... Just talk about something random.. Ask her what she's up to. Tell her about what happened to you on a day. If you two do talk.. Start over. What happened in the past is in the past.
3rd ... Stop whining. Seriously. We all know your heart broken. We all have been there.. We all know how the pain is the worse pain you will ever feel.. But.. Every wound has to be healed. Find something that makes you happy. Something you did all the time before you met her. And start it back up... Push yourself to do that activiy for 10 minutes. The next day, try 15 minutes. Pretty soon, you'll be participating in that activity longer each time.
You need to find happiness that doesn't require someone in your life. Its healthy for you, its healthy for your next relationship... And who knows.. Maybe you PROOVING to her that you can handle yourself.. That you are a strong, capable person will have her WANT to talk to you again.
Stop living in the past and starting living NOW. If you want your girl back, well, she'll have to want to come back first... Then you need to stop crying. Her next move is go go out and have fun... Not sit on the phone or be plagued with text messages of, "WHY won't YOU TALK TO ME". Leave her alone. She needs to think and sort through things without your opinion and interference. If she wants to be with you again, if she decided that you are her one and only, she'll make the move. You're not going to make that choice for her.
How would you feel if you broke up with someone... You were confused, not sure if that was the right choice... And the person you broke up with was pestering you every day? Pretty irritated.
The above answer seemed pretty damn good. I'll add my 2 cents. I've been dating an amazing girl for 1 year and 3 months. We had some rough patches but were pretty good at trying to fix them. The longest we didn't talk for was a week. But about four days ago she said she was leaving. And that maybe we'd meet later down the road. We always talked of getting married and honestly I think I should have. She was awesome. Cooked for me, did my laundry, even cleaned my friends apt for 8hrs for free lol! Oh and she was sooooooo hot. Honestly all my friends were jealous. I didn't even have to try to get her either. She just liked me
Anyways it sucks now though. I called her around 4 or 5 days ago and she didn't answer. I've been trying to not think of it. I'm starting to go to the gym and doing cardio to get in shape. I just have to show her that she is missing out and its her loss if she doesn't have me. I think talking to some other girls and getting them to like you will make your girlfriend jealous and then she'll want you back. When she knows other girls want you, she'll want you too! (hopefully) And who knows maybe is a better girl for you!
