If you think that by being friends with your ex, you can stay in their lives and hopefully get back together again, you are just plain wrong. By being friends you are not giving yourself and your ex enough time and space to heal. Not to mention, you will probably end up getting friendzoned by your ex. You could end up listening to your ex complaining about their new lovers (cue : Ex-girlfriends)  or they might propose being friends with benefits (cue: Ex-boyfriends).
Act like nothing is wrong. Even if your guts are tumbling like clothes in a washing machine, try not to let her know. She's probably not going to want you back if you're acting depressed, mopey, or sulky. Make sure you're laughing and genuinely trying to have a good time. You might find that you've become a happier person along the way. If you are feeling depressed, surround yourself with friends or family. Don't wait alone in a corner and just hope for her to come back to you.

Apologize. Think deeply about anything you did or didn't do that somehow contributed to the downfall of the relationship, and clean the slate by giving your ex a proper apology. Take full responsibility for the offense, without blaming your ex, giving excuses, or expecting an apology (or even forgiveness) in return. It may very well be that your ex contributed to the situation, but you cannot apologize for someone else; you can only apologize for yourself. Leave him or her out of it and odds are the apology will be reciprocated.
We also know that there are exceptions. There are relationships that probably should not stay together, such as those with physical violence, cruel and ongoing verbal abuse, extreme anger management issues, or long-term unaddressed substance abuse, for example. If you're in a situation like that, please eek the help of your local crisis management center.
