My ex with BPD send me this video/tiktok

I don't know what I should make of this or what she means..? Or am I just overthinking? We still remain friends and thought about getting back together but both don't know if we should, if that helps someone helping me. Btw, my name is Bob, so you know, Bob the builder, that's where that comes from...
