-They use to obviously have a sexual relationship and she still finds him attractive, she told him she doesn't have feelings for him anymore.

-She complains that she doesn't like texting him and he always messages her, but she is genuinely hates him and doesn't want to have anything to do with him.

-She will be hanging out with him soon for a final goodbye because he'll be moving out of the United States.
