Ever since she broke up her sincere and lovely relationship with an incredibly witty and smart Jose Mourinho, this girl Chelsea is acting like a bitch. She isn't satisfied with anyone since then. And at the slightest sign of trouble in the affair or when her grades in school falls a bit low, she dumps her boyfriend and looks elsewhere to support her emotional instability. She was with some good guys (Carlo) and some really handsome guys (AVB). There was a even a guy who she actually liked, but was committed elsewhere (Guus).
Then there was a very decent guy called RDM who took her to places she had never been before but always longed to. Eventually that relation too end up badly, maybe she thought it was getting serious than she thought it would. She was afraid of falling in love with him and being in a long term relationship which might prevent her from being able to receive her old true lover when he comes back. Maybe she thought this guy being so decent, deserved something better than her.
Well, now she is with a half decent guy and a rough handler. An ex boyfriend of one of her biggest adversaries. Someone whom she hated once and probably still hates but she is happy to spend time with him because she knows she can dump him any time and will definitely do that when her true love returns. She doesn't want an emotional attachment with anyone before that, but always needs someone to handle her emotions and to lean a shoulder on.
Deep inside, she is really in love with the special one. And it's this love, combined with her insecurities that made her the bitch she is now. We don't have to worry about her, she's going to be fine once she is in the right hands. It's going to be some wait, but deserved wait.
P.S, This is not an original Idea and is inspired from a comment written by "snackage" in the page Roberto di Matteo sacked, which was - "Ever since Mourinho left Chelsea has been kinda of a bitch, breaking up with our managers as soon as the relationship hot a rough patch." Thanks to Snackage and to those who read this post till this point.
