Ex of 4 years recently split up and I've been more or less indifferent. I messaged her, telling her I'm open to watch a movie, to which she replies with attitude and says 'I'm going to get dick from my boyfriend ' followed by ":)". I ignored that message and said the movie's still on, then I ended the conversation with 'have a good afternoon', she replies 'I definitely will'

There's been history of her telling me she'd try to make exes either mad at her, beg for her or insult her

I refrained and kept my composure. Is this her way of a shit test or a lost cause?
