Consent. Scenario 13 of 34. Your own boundaries
Goodnight x
A few weeks ago you told your friend Chloe that you only see her as a friend. She said she understood.
Since then she has texted "goodnight x" every night, sends heart emojis, and jokes in messages about the two of you being "basically a couple". You like her as a friend. The messages are making you uncomfortable.
The principle
A boundary can be crossed by anyone, in small and friendly-looking ways. You are allowed to say it a second time, and you do not have to manage the other person's feelings by going along with it.
