Case of the ex.

So i was at the pub on saturday night with some friends, and i recieved a phone call from my ex. The funny thing is it wasn't my ex- girlfriend, but my ex-boyfriend whom i had left for my ex-girlfriend. The bizzarr and incoherent call left me pondering the question, why do ex's call you when they are lonely? Why do they call you at all?. Surely they have friends who they can talk to, so why do they feel the need to ring you and bring up the past and all the reasons you left them in the first place? It must be a thing they can sense, when you are finnally happy and have moved on, they ring you (usually drunk) and freak you out with their baggage. This is just one in a string of calls i have had from ex's in the past month. My recently ex-girlfrind has also called me to play some mind games. What do they expect from you these ex's?, do they think after all this time that you might have changed your mind realised the error of your ways and want them back?, or do they think its fun to play games and like juviniles throw tantrums when they don't hear what they want to hear?. I'm sure whatever it is they want i am not the right person to give it to them.
