So I showed my friend this guy I really like and?

She added him on instagram from the handle on the picture I had shown her without me knowing, and hit him up on dm a week later. When I saw she had suddenly started following him, her excuse was she was "hitting him up to test him to see if he is good for me." She keeps liking his photos as well even though me and him were already talking. She already has a boyfriend, who is my ex. Should I drop her? How should I drop her
