Even though this situation may be extremely distressful, it holds an opportunity for you to learn something about yourself, the ex-boyfriend, and the situation that you have fallen into. Try to make sense out of yourself and don't become exasperated because you cannot figure out the motives and intentions of the Ex. Keep a journal and log all your thoughts and feelings. By writing through your difficult emotions, you'll discover hidden strengths, feelings and insights. This is a golden opportunity to learn.
