How can I get him back?

You can't force someone to want to be with you. If you were too clingy, and the other person didn't like that, then there is nothing you can do. Next time, give the guy some space. You and him don't need to be around each other every second of every day. You need to learn to trust more, and have your own life and let him have his, then, when you are together your love comes from wanting to be together rather than a craving, clingy, need.

Now since he has dumped you, its better you dont run behind his back. Cause may be he doesn't deserve you. Rethink about everything you had with him and also see to yourself that you have also learned something new from the relationship. So try to be what you want to be and also an example for the society. Look for another one who is better adjustable to you. Better luck:)

give him space spend time with your friends than ask him if you guys can hang out and try to smooth him back in and show him that your not clingy by doing your own things and giving him his own time

first off act like you don't care because if still trying to get him back that means your trying to hold on to him and thats the exact reason why he dumped you if you act like don't care he will realize he was wrong and when comes crawlnig back just say no !

Stop being too clingy then...

what you do is, you go to his house in the dead of night, kidnap him, tie him up and dont let him leave unless he agrees to take you back.

offer him your flowers.. XD
