It is ok that you still have feelings for this man, but you shouldn't interfere with anyone's relationship. But give it some time because if he still had feelings for you, then he would probably let you know. And if he doesn't, then he probably doesn't want to tell you because things are going good for him & he doesn't want to start over. Just give it some time.
