It is amazing how powerful the lure of the forbidden or unattainable is.
Just think about having to deny yourself something you love, and how your every thought is suddenly centered on that thing you cannot have.
Relationships that have ended prematurely can be resuscitated by this manner as well.
Want to make your ex miss you? Then make yourself the most desirable thing in their world, by being something they think they cannot have.
In a way, this is like changing roles with your ex.
You've missed your them like crazy, it's time to make your ex miss you like crazy too! When they try to contact you, ignore them.
The more they call, the more aloof you must be.
When you do speak to them, let them know of all the fun and fabulous things that are going on in your life or clam up and simply end the conversation as soon as possible.
Your ex will be confounded by the sudden change in attitude and will be thinking about you non-stop.
You must remember to be strong during this time, one vulnerable moment could set you back in getting your ex to miss you and come begging for another chance.
Another tip is to have complete control over your emotions.
Chances are, your ex will say and do things specifically designed to elicit an emotional response from you, and you should NOT give that to them.
Your ex wants to know that you still love them, it boosts their ego - but don't give them the satisfaction.
Say they make plans with you and blow you off, then call you at some later time to apologize - play it off.
Pretend you didn't even remember having had plans to begin with.
Your seeming lack of concern about your ex is likely driving them mad.
You ex will remember how wonderful being with you was and wonder why you suddenly don't act the same way as you once did.
Remembering all the good times and realizing that the chance to get you back may be waning away is going to make your ex miss you desperately.
They will do whatever they can to find a way to get back into your good graces and make you love them again.
