Inappropriate texts from colleague?

[happierthannever]

A colleague I used to be friends with (nothing sinister I just slowly drifted away from her as I started to find her very suffocating) sent me messages on Monday saying I was a horrible person etc

I just want to quit my job, these messages have made me feel so uncomfortable.

Do you have a HR dept or some sort of harrassment policy? You should lodge a grievance with your employer about her, why should you quit your job because of her actions?

@happierthannever - is there any more context here ?

More context needed please.

A one off you might be prepared to ignore, but anything more I suggest is a matter for HR.

Definitely one for HR but what's the back story?
