• Don't forget the past; utilize it. Acknowledge that you will move beyond any painful experiences and focus on future relationship success.
If the break up was your decision, bear in mind that thinking about all the good times you had may cause you to forget the reason for why you broke it off. It's very common to overly romanticize the good parts of a relationship, convincing yourself that maybe the bad parts weren't so bad after all, maybe you could live with them. Or that maybe if your ex could know just how you feel, s/he wouldn't want to break up after all. Don't play this game with yourself. Accept the situation and move on.
Even if you and your ex have decided to stay friends, take a complete break from each other immediately after the breakup. That means no seeing each other, no phone calls, no e-mails, no Instant Messaging, and most importantly, no sex - not necessarily as a permanent measure (except where sex is concerned), but until you feel that you can converse with him/her like a normal person, without an ulterior motive (and yes, wanting to get back together counts as an ulterior motive).
Think through everything thoroughly, but not obsessively. Go ahead and mull it over, as many times as necessary, within reason. Consider all the reasons you two broke up. Even if it seems there wasn't a good reason, there certainly was one - and probably more than one. Understand that you enjoyed one another for a while, but even though everything seemed okay to you, if the relationship was not what your partner wanted for life, it would have ended eventually, no matter what. In this case, better sooner than later.
Deal with the hate phase. This is where you want to just scream because you are so angry, even furious. The amount of anger you feel all depends on how bad the split was, how it occurred (was there infidelity? That makes it worse), and how long it took to make the final break. There may be feelings of resentment at your ex for wasting your time. You may realize the breakup was inevitable (hindsight will reveal clues you failed to notice at the time). You may even feel like you hate yourself, but let go of that feeling fast! It's a waste of time to be hating and ripping yourself apart over something you no longer have the power to change.
