Being alone is one of humanity's greatest fears. It affects its sufferers most of their lives, and it can't be cured by any medical treatment or medicine.   If you do not want to become a decrepit old drone years from now because you let go of that one person that you want to spend eternity with, now is the time to take action before it becomes too late and she has moved on to someone new.  Circumstances such as this require you to stop at nothing to get her back, as the more time you allow to pass, the more likely she'll be gone forever. This may require you to risk everything (including your pride) for the sake of love.

If you're a guy, you could always try a little romance to get her back, but this is only a possibility if that was what was missing in the first place. If this is true for you, regaining your relationship will be fairly simple as there is a multitude of expressions from which to select. If your relationship ended because of more serious problems, however, it may take much more effort on your part to mend it.

Taking into account all the problems that you have as a couple, pick out those that you think you can fix on your own, such as those that are obviously caused by your shortcomings.  The problems your relationship has that are shared by your partner will require a joint resolution.  In order to get your ex back under the right circumstances, you should have the perfect timing for everything.   Remember the saying, to each its own time because it cannot be more applicable in relationships especially repairing them, or at least trying to. 

Sometimes a girl or boy will try to get back together with their exs and things just don't work out.   It should not be due to your lack of trying though because that is simply unforgivable.  but, you can only control how much effort you exert because your ex will need to do her part as well if the relationship is to survive.

If all the flowers and chocolates are not working, you should move on to more aggressive actions such as bold invitations to dinner or lunch and even the occasional surprise cup of latte that she likes so much. 

Do not for a moment expect these simple tokens of your affections to hook your ex's heart again, however. Your ex will most likely desire a more permanent adjustment in your personality in addition to all the romantic things you are ready to do to reunite the two of you together. Lovers are typically more intelligent once they've experienced loss, so be prepared. You should be more intelligent as well, and once you realize what you've lost, you will be able to determine the correct path to take in attempting to win back your former lover.
