Ohhhh man, where do I start.
Ok, first of all, you gotta get a hold of yourself. You're a complete mess right now, and there is no way you can win her back in your current state. I'm sure she loves you, but the needy desperate state you're in now will only drive her away. BREATHE. Go to a gym and beat the shit out of something if you need to. Let the frustration out and get your head together.
Now that you have your head together, let's sort out some facts.
1.) You broke up with her first.
2.) You didn't enjoy being single, and realized you want her back.
3.) She had to get over you since you initiated the breakup (you didn't give yourself the chance to get over her because you thought she'd be there anytime).
4.) She still loves you.
So, you want her back. This means you have to
make her feel that life with you is better than life without you.
Is what you're doing right now going to help you in this goal? HELL NO. You're acting needy, desperate, clingy, etc. At this point, why would she want to be with you? She's not attracted to a clingy whiny guy whose world is falling apart because she's not in it...she's attracted to YOU. So who are you? What is it that made her fall in love with you in the first place?
You gotta remember who it is she fell in love with and BE HIM. No begging, no pleading, no flowers (yeah, they're nice, but they're not gonna help you here). You have to show her that you are
fine without her, but choose to have her in your life.
So how do you do that? There may be a couple of ways, but they'll require major self-discipline.
1.) Cut all contact with her now. Go out. Reclaim your life. Find your passions and pursue them. Start talking to other chicks again. The main point is for you to really realize that you
will be fine without this girl. This shit isn't gonna work out if you can't live without her. You'll be too needy and you'll drive her away. The only way you two can be happy together is if you choose to have her out of desire and not out of necessity.
2.) If you're not willing to do that, at least tone down the neediness. Don't beg her to go out. Talk to her like she's your friend. Stay calm and unreactive. Be a presense in her life, but don't push for a relationship. If you play it cool enough, she may come to you. Then ease into the relationship and maintain the frame you had when you two fell in love.
In either case, you will need major self-discipline and a firm hold on your
inner game, and there is no guarantee that she'll come back.
You have to be fine with that outcome. Your current mentality of NEEDING her will never get her back.
I'm sure most people will call this one-itis, and that's what it is. But if you detach yourself from the outcome and regain your emotional control (monumental task, I know), there may be a chance of fixing this.
Good luck,
Rogue
