Trying to get back at your ex, or attempting to make them jealous is not a wise path to take
. In fact, these are some of the worst things that you can possibly do. Your ex is likely to interpret this kind of behaviour as a sign that you have already moved on and they should do likewise.Whilst you do want your ex to see that you're doing ok, obviously you don't want to persuade them to completely move on if your ideal scenario is a reconciliation. Let your ex see how self-confident and strong you are, and they may well feel thay they should give the relationship another chance.
