How to brainwash myself not to think of her anymore!!?

My situation is a bit of a strange one but here goes. I recently moved over to Bahrain in the middle east coming from London where i had just finished up my masters in an Information technology course and post that was unemployed for around 9 months which created a lot uncertainty and depression when i was there. Now what really stemmed it of at the time was my girlfriend who had currently held a job 2 months after i graduated and most of my friends were already in work. I started to gain this anger based on jealousy that was beginning to eat me up from inside due to her work and her not haing enough time for me. I became angry a lot and started to take out my problems on her due to her low commitment from her end and my constant attention i was giving her (dropping her to work in the morning, picking her up, takign her out for dinner, doing her chores or activities that she wasnt able to do cause of her work during the day). I was gettign worse and worse and was applyin to jobs nearly every day while helping my father out with his business which made me feel younger such as kid feels due to my treatment from my dad. It was 9 months later where i managed to secure an offer for a company overseas in Bahrain where i am writing this from within finance involving various rotations for one year to becoming permanent within a particular area. Since i have beeen here i havent been given much to do and am stil not content with the situation as well as this finishing up early at around 4pm every day which has caused even more jealousy and anger in my heart. My girlfriend is what is on my mind every day thinkin that she's always doing much more than i am and she' s better off due to my lack of accountability within the organization i am in now. As well as this llately i get no attention from her espeially that there is a 3 hr time difference so i get a call once a day around 10pm my time which i find ridiculous and begin to sense lonliness within myself and imagining her being busy at work and conversing with others while im stuck at home at 4pm in the afternoon with nothing to do. I just feel she doesnt care as much as about me as she does anymore and is constantly probing me for when i can come back to London me having it in my head that i apprehend that she thinks everything is infeior to that country!! maybe thats just me.. She has visited me twice here though and now and again sends me some nice messages however when she goes back i feel she forgets me and is more concerned about her work and family rather than me. She driving me to the brink of insanity and hurting me internally cause of where i am now and where she is thinking to myself she will always be better off than me no matter what job i take or do. there is nothing i can do to take her of mumind apart from being given decent work to be done at my workplae and occupying myself in that manner and the jealosuy is eating me up from inside. I know she loves me deep down but does not show it and recently announced a break between us which i feel she is not finding it hard to go through calling me once a day whereas i text and call her all day with no response. Is it me being over the top or is it her something from her end? How do i brainwash myself not to love her anymore?
