My ex, who ghosted me for acting beta and needy as possible saw i'm having success (on social media), then proceeds to message me the following:

I can't sleep and you got in my head next to a song, i don't know why, but stop.

Goodbye, take care and i'm proud of you

i didn't answer and 5 days later (today) i called her at 1 am to thank her (as an unpredictable movement) but didn't pick up the phone (obviously)

I have been working on my business so i barely reply to messages, Why does she do this?

thank you in advance.
