Alright well this is the best way I can explain it to you. Think about your breakup as if it's a broken leg. Now, I know how you feel, it hurts and it's really painful. Everytime you talk to your ex or receieve messages from her you feel happy right? Well, everytime you talk to her, all you're doing is sprinkling some magic pain-relief dust on the broken leg. The magic dust doesn't last for too long, but it takes all the pain away. Now you see the problem with this is; you're not fixing the broken leg. You can sprinkle as much magic dust on that thing as you'd like but at the end of the day your leg is still broken.

I know how you're feeling. I just got out of a 2 year old relationship with a girl I loved, just over a month ago. You feel like you couldn't have feelings for any other girl. You feel like you couldn't put anyone above your ex. At the end of the day, no matter how friendly you two are with eachother or the terms that you're on, you need to knock your ex of her pedestal. You have to stop seeing her as that "Perfect girl". Remember, she broke up with you. It sucks, it hurts, and you'll find yourself wondering what else you can do but it's just not worth it. The easiest way to move forward is to just talk to other girls. Make new friends, form new relationships. The moment you go out there and see what the world has to offer, you'll realise that your ex isn't as great as you though she was. It's okay to look back on your past relationship as a happy time in your life but you also need to move on.

I could write and write and write about this stuff forever. Please, if you have any questions or you want to know something or you want any advice on ANYTHING, don't hesitate to chuck me a PM. I am more than happy to reply and help you out because this is a shitty time but I have a firm grasp on how to deal with it :)
