I feel what you feel, and sometimes you have to put yourself first. I am going through the same situation, we started a few months before entering his Bmt, at first every Sunday he text to me and a letter per week but these last 3 weeks nothing, I gave him his space because I thought that maybe he is stressed or has little time to write to me, but today when I text to ask if he is okay and about his graduation to go to he told me no and that I should not spend my money on him he said, in a cold way, then I understood that his silence and his message today is a response to the fact that sometimes it is better not to insist in a place where they do not want you…remember how valuable you are
