My ex is crazy or something she seriously wont leave me alone. Help?

the worst thing is telling her off. shes gonna want to talk to you more. if i were you i would tell her boyfriend and make him mad. then i would start hanging out with her friends. ignore her messages and fb things and not work yourself up if you honestly dont care about her. get a new girlfriend or something haha than your girl can do all the fighting for you. i recommend not having anymore serious relationships though till your in your last years of college you seem like a nice guy. im like going through the same thing almost haha
