Breaking up is a painful and difficult thing to do. It's pretty hard (dare I say impossible?) thing and most don't have the stomach or the self control or the understanding to do it in one day, one instant. So they make it a gradual thing. She feels incredibly guilty, I know she does. Even if you were a dick. The time you spent building the bond you have/had, it takes it's toll on both of you. They will say things like "We will talk in a couple weeks, see where we are then, etc. etc.". The line I got from my ex was "You are the one, just not now." It doesn't matter what they say, you have to look at their actions. And their actions were dumping you. They chose to end building a life together with you to be apart, away from you. It doesn't match up and you shouldn't think for a second that a talk in two weeks will fix everything. If you even talk at all. I say this because that is the reality of the situation.
I mean think about it. Why would she dump you if she wanted to just get back together? What would be the point?
You have to accept that this relationship is over. You tried apologizing. I'm sure you had a speech or two. It didn't work. This is what she wanted. So let her deal with the consequences. Being there for her is actually pushing her away, if it makes sense at all. Knowing that you will always be there for her will help give her a cushion and the confidence to move forward. Because that is what she is doing. She is out there looking for your replacement right now. Many girls don't have the strength to break up UNLESS they have somebody else to jump to that is ready and waiting for them. Sorry if it's the scary truth.
The first thing you should be concerned about is not how to get her back, but how to find happiness, fun, everything that seemed great before, only without her. This is if you really value you and putting yourself first. And I know you want to put yourself first because no matter how much she doesn't want you in her life, you do want her. You did it before you had her in your life. You can do it again. With you having fun and living life without her in it, she will see the person you were before that she fell in love with in the first place. But that's the point of cutting contact and giving her space. To get her out of your system and start moving forward. Easier said than done and it's something you have to commit to EVERY SINGLE DAY. It's a battle every day. You start looking back, you keep looking at her facebook, you keep trying to talk to her, you are just going to fall back into the horrible feeling you are feeling right now.
Fall off the face of the planet. Let the two week period go by, if she talks to you, take it from there. You don't need to talk to her so if she doesn't, no big deal. No matter how this works out, you will be okay. She is not the only person on this Earth for you.
And please, don't make this any harder on yourself and start forgiving yourself as well. You made mistakes, you weren't perfect. But you recognize those mistakes and are working on correcting them, right? Would you say she never made a mistake? Of course she did, she contributed as well. Your experience from this, your self realization increased your self awareness, and you are a stronger, better person for it.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
