There comes a big vacuum in one's life after a break-up.
It's very annoying when you are the lonely one and your ex-partner has found somebody else and is having a good time. The fact that my ex is now dating his ex-ex and painting the town red with her is so irritating. I don't know what kind of relationship they have- both of them are selfish and superficial people- but still- it's just so annoying.
I guess that is the hardest part to digest.
He fools me, he lies to me, he takes me for a ride, he breaks my heart in an extremely cruel manner- and- nothing happens to him! He gets together with his ex and life is just so perfect for him. To top it all, he gets a promotion, and makes a lot of money, and everyone thinks he and his old-now-renewed girl are a perfect couple. How picture-perfect! How damn UNFAIR!!!
"It's not fair!!!" aah well- but one needs to just accept and digest these things believing that in the end, somehow everything will balance and justice will be done in some inexplicable way.
