Why is his crazy ex copying me?

He dated this girl for like 3 weeks a year ago and she copies everything I do. Wtf is wrong with her? My boyfriend is so crazy about me that he copies me lol and my interest. What to think about all of this? I've cursed this hoe out before because I think she thinks she will get my boyfriend back. No way! Why would this girl copy me like this? Also me and my boyfriend liked each other because this girl ever dated him.
