Am I being over sensitive about the situation this morning...?

Ive been working at some crappy catering company for a month on minimum wage but I havent complained just recently started needing more work because of money issues. My bf knew I was going for an informal job interview this morning and didnt even wish we luck or supportive kiss and say goodbye before he went off to work. I know it sounds stupid when Im saying it now but its bugged me a bit to the point where I want to text him going 'I know your tired lately but could ve done with some luck this morning', I just dont want to be causing stress out of nothing though
