Boy problems

I am 16 and i really like a boy from my school. At the start of our friendship we have told eachother that we like the other but it went down hill a couple months later when i have already started developing stronger feelings he tells me that he is still in love with his girlfriend i know for a fact that he is a good boy and he is so sensitive. His girlfriend, even though he tells me she is not his girlfriend has broken his heart numerous times. He is always giving hints that he likes me but he meets her every week... what do i do my exams are in a couple of months and this whole situation is making my life worse
