How do I get this girl off my back?

[Emily]

Alright so I'm a girl and I was thinking about how I would want a guy to deal with this situation, but honestly there is no way your gonna get her to stop without her getting upset.
You could always try just not accepting any of her invites and hopes she gets the idea ( no promises that will work or keep her from getting upset)
Or you could always talk to her about things you hate about a girl and bring up girls who are constantly trying to talk or hang out, that are clingy or wont leave you alone. ( Still no promises there )
BUT these are indirect and might not work, so the best way to deal with this would probably just say
" I honestly don't want to embarrass you or make you upset in anyway, your a super nice girl but your constant messaging is kind of out of control maybe you could lay off a bit? " Obviously she's gonna get upset, but at least you weren't a jerk about it.
