Then it begins to happen. Your ex seems to be sending out signals that a kiss-and-make-up scene is on the cards. The emotional turmoil that this ignites in you should be handled VERY carefully, because you don't want to look too much like a puppet whose strings they still control. So some aloofness (yes, hide that wildly beating heart of yours) is in order.
It may be helpful to think about what is happening for them that is resulting in them sending out these come hither signs.
1. You have built a history together, whether a long or short one, but there are places, people and situations that trigger memories for your ex, possibly even wistful ones
2. They may genuinely be wondering if they have made a bad decision in letting you go. Absence may be making their heart feel more fondly of you. Yes, this is the one we all dream about!
However, their motives may not always be as pure as the first two. Consider these:
3. They may wish to test you, to see how easily they can control you. They're just trying to feed their ego and have no intentions of actually reconciling with you.
4. Maybe they are at a loose end, with no one else on the scene, and are just expecting you to fill a temporary gap in their life until they get a better offer. For women, they expect at least a free meal. For men, the least they expect is free sex.
5. And, perhaps the most cruel of all, they are out to break your heart all over again, either in revenge for something they think you've done to them, or maybe even because they're a complete sociopath. About ten percent of our population, unfortunately, fall into this group (and yes, it's most often men).
Be careful in taking your time in responding to this situation. If your ex's motives are honorable, this will increase their respect and their longing for you. If you're ex's motives are anything less than honorable, your delay will surely get under their skin and annoy them.
Be very careful in making your decision, and don't be too eager to re-start this relationship. You may be unwittingly walking right into a trap.
