Trying to make your ex jealous, or doing things to get back at your ex are probably the worst things you can do if you want to win back your ex
. Such actions will likely indicate to your ex that you have already moved on and he or she should also. Although you want to show your ex that you are doing ok, you don't want to give them the impression that he or she should move on, not if you truly want to get back together. Letting your ex see how self confident and strong you are may very well motivate your ex to think about reconciling.
