So, I want to ask this person what's up but at the same time I don't want to ask. But anyone that is good at this stuff what do you think?

So there is this co-worker, soon to be a former co-worker, because I am leaving. When I somewhat dated this girl, we would talk on occasion. Then randomly, she started acting weird and started being a jerk, like yelling things at me when passed, but that was as far as it went for the time. I didn't care really at all about what she was saying because it was about stuff I didn't care too much about. Then one day, I am shopping, and I go in a lane and am talking to a friend. She took one of those sticks that separate transactions and hit me with it. I literally had no idea where that came from, like why she did it. But I didn't do anything because 1. there were customers around and 2. because I'm not really the type to start a brawl over this. But just recently, she's started talking nicer to me and saying hi to me, and texting me. Like it's a complete 180 super weird. I don't know if anyone has had this happen, but if it has and you found out what it was, please let me know.
