dear ..... thanks for your letter, i was sorry to hear your news, it was quite a shock because I know how in love you had been, it sounds a really difficult situation, especially because you can´t concentrate on studying for your exams thinking about your ex-boyfriend, try not to worry too much about it, after all, you have to hold on only for two months, i know you must be really worried about your situation , because i had a similar experience .Is there anything at all i can do? If you want to, you ´d be welcome to come and talk about your problem at my house, do keep in touch, give me a ring if want to talk it over.
