Now its time to practice theory test

My girlfriend has just told me it"s over. She says I don"t spend enough time with her, don"t text or phone her every evening, constantly refuse to go on holiday with her and do not come to her parties. Well, of course there is a grain of truth in a these accusations. I haven"t had that much free time recently. I have to practice theory test because I"m taking my exams next month. I"m also taking lots of practical driving lessons at the moment. Sometimes I see my instructor twice a day, in the morning and in the afternoon. I"m also studying for my exams at school. I"ve had some problems with History and Geography recently. Why does she expect me to be at her beck and call all the time? My life has become so stressful that I have started catching colds more often. That"s why I skip some of her parties, and she tends to make a lot, believe me. I don"t know if I should take this seriously. I still want to be with her, but I don"t know it will be possible at this point. Our lifestyles are completely different and I don"t believe I could change mine that much. I have to go now, anyway. I have to practice theory test and then revise for my History test. I wonder if she remembers we"re taking a test tomorrow. I won"t tell her, of course. If she wants to make a party today or go to a pub with her friends, I won"t interfere.
