sometimes. If he has already moved on then maybe thats your answer, I think if he really wanted to be with you he wouldnt be with anyone else. Try and find out how he acts with her, she's probably a rebound. Give it some time and see what happens, and if you still want him back if you really love him and you think he still loves you, try again but if he turns you down accept it. Dont waste your time trying to get him back just focus on you. You deserve someone who will want you, the way you want them. Go do things have fun get your mind off him. Sometimes when they see you dont care anymore they start wanting you back. But if you take really good care of yourself in the end you'll be on top and you wont even want him anymore then he'll be the one missing.
