What's is my ex trying to do?

Today she hugged me or whatever the F'ck she was trying to di. she said "I was trying to the leg trip thing" and kept holding me. I was being nice ignoring it but I'm pissed she did that in front of a girl I like. The girl was like "aww she's hugging you." at the end of the day she said goob bye buddy and hugged me. I was kinda like ok... What the fudge is she trying to do we"re going to different highscools in 2 days.
