I feel your frustration and I feel your pain. The feelings that develop because of a relationship breakdown are a complete mish mash, and some that you probably won't experience again. The weird thing you are probably finding is that throughout the course of any 24 hours, you feel every emotion you have ever felt in your life.
You smile with happiness as you reminisce about the good times you had. Then quickly you fill with rage as you imagine you're ex partner starting a relationship with someone else. You felt connected and full of life, yet now you feel sad, empty and alone, almost like a part of you is missing.
I know you must feel right now that there is no hope, no chance of getting the love of your life back - but there is! All you have to do is put in that last little bit of fight, then if it doesn't work, try and move on with your life.
The first thing to do is junk all the sites you have bookmarked with free relationship advice. The creators have probably never even had a serious relationship, let alone been dumped. If they don't know how you feel, how can they help you?
The next thing you need to do is follow steps in a proven system. A individual that has gone through the exact same process that you have is a lot more likely to be able to help you than someone that hasn't. Follow a step by step system and that should show you getting an ex back is possible within 72 hours!
