Perhaps right now I'd be best to stop talking with anyone associated with him because I'm sure they are bound to ask that "So, what happen?" questions and want to take a guess who is probably going to know about what you all talked about? It's all about self-control. I will openly admit I checked my ex's Facebook nearly everyday for over 2 months after the breakup and I can tell you it does nothing but cause you pain and anger. That's why I stopped. It will not help you move on. Any time you feel the urge to check his page, DON'T. STOP. Take a breath and ask yourself, what's the point and why do I want to cause myself miserable pain? Because I'm sure once you read all the stuff he's not doing with you or posting pictures of his new girl and seeing that "In a Relationship with X Person" you're just going to be torn up about it. You know you will be yet you can't help yourself because you have lost your self-control. I'm not sure what you could do but instead of checking his page do something fun on the PC... play a game or distract yourself with something positive. One day you will be able to look at his page and maybe then you just won't care anymore and I'd just be like any other friend on your Facebook but obviously that day isn't today and certainly not for awhile.
Don't think about if things are meant to be you'll find your way back to each other. That's not healthy thinking because the thought of getting back together will be on your mind. It is not impossible and there is success stories on people getting back together but in my opinion enough time must pass before such a task can be tackled. But you absolutely don't want to be thinking that right now. What you want to be thinking is just focusing on yourself right now and your own happiness. I know it's hard as heck.. it's supposed to be. Life is challenging you and you must accept this challenge and not accept defeat. In the end you'll be a stronger woman.
