Your ex has been in the spotlight for too long.
Yes, you are putting your ex in some sort of spotlight by paying him/her all of this attention that they really do not need right now.
What your ex really needs is for you to knock the floor right out from underneath them so that they can finally see what is what! Unless you knock your ex's socks off, by doing exactly the opposite of what they expect, your ex will never be that inclined to want you back.
So, here is how to get your ex crazily mad for you...
Ignore/brush aside/cut off contact/disregard/neglect- whatever term or word you want to give it, do this to your ex.
This means no calling, no constantly staring at your ex or their profiles online, no talking about your ex to anyone...
especially your ex; and just plain going cold on your ex.
When you do this, it is impossible for your ex to take you for granted anymore.
Your ex will have no choice but to start missing you over time, because you just rejected them! No one likes rejection and especially you took away something your ex always had so easily (yourself), your ex will burn to get you back.
No one likes losing something they thought they bagged! Your attention and time is important for your ex to feel good, because he/she was sure getting a good ego boost from your attention previously! Watch as your ex tries hard to get you, because now you are playing hard to get, and now you are not so easy!
