Just because someone ended a relationship does not mean they absolutely have no more feelings for you. The one advantage you have, as someone’s ex, is that you have history with them and something that once existed can be reignited.
With a bit of tact, patience and perseverance, you should be able to convince your ex to come back to you. Here are a few ways to do this;
1. Give them time: It is easy, while feeling the desperation of a jilted lover, to want to immediately do everything within you power to get them back. But desperation would only turn them further away from you.
If you want any chance at getting them back, accept the breakup at the time and give your ex the space he/she needs. Handling things maturely is the first step in putting a doubt in their minds that they have made the wrong decision.
