My boyfriend of 1.5 yrs has just dumped me without any warning. I had no idea he was unhappy as we had only returned from holidays about 6 weeks previous & had brill time. In 10 mins he told me he was breaking up with me and I was in such shock it didn't sink in until the next day. I have so many questions to ask him but I don't think he'll contact me. Should I send him a letter in a few wks time telling him how I feel?
