Ok, so
you dont want to come out looking the bad guy, introduce her to a friend she
is never going to see again(or pay a random $10 to do it) have a conversationg then walk into an nearby room, making sure she can hear you have the friend tell you how clingy she is you deny it outright, the friend insists you refuse the friend says something like "you serious, theres not been a moment when she seemed a little clingy?"
then you say, she might be a little clingy like when she... (fill in the sentence, i got some premade ones by the way)
...insists on holding my hand
...insists on me writing her poetry
...insists on taking locks of my hair for her shrine
then the friend says "see? she's clingy dude! i reckon you should dump her!"
and you say "no,
she may
be a little
clingy but i like her (or something)"
She's going to hate the friend, like you for defending her and cling a bit less.
your welcome
