Why don't you find time if you really want to talk to her?
If you already don't have time then why try to squeeze in another thing?
Because stalkers are homicidal maniacs and because they're evil and full of poison. Stalkers don't care about anyone's life or wellbeing.
They are obsessed. They have a hard time letting go. They are dillusional. They believe that they are in a relationship of some sort with said person. Etc.
