Getting your ex to notice you is the first step you need to focus on if you want your ex to desire you again.
You can do this by looking great - according to your ex's standards.
You know, everyone has his or her own trigger point - it's that one thing that makes you look twice at another person.
The thing is, not everyone has the same trigger point.
You need to know what triggers your ex's interest, and work on being or having that kind of appeal.
It's shouldn't be too hard because you've done it once before.
The next thing you need to do is believe in yourself.
If you walk around dejected, it gives a really negative aura that will not attract anyone, much more your ex.
Rally your friends to help you by asking them to spread the word that you're hot.
Even if you have gone through so much, you're now back on your feet.
You will also need to get back into the social setting where your ex likes to go and hang out.
One rather sneaky trick that you can try when you're out and partying is to fake a budding romance.
You can do this with a trusted friend who will flirt with you in front of your ex.
Word of caution, don't let it get out of hand, and tell your friend not to go overboard.
You don't want to look like you've replaced your ex with someone else.
You should also be ready to accept defeat.
If your ex does not even show the slightest hint of interest, then maybe it's time to move on.
