Let's see, your female friend makes a 'joke' video of the two of you on a supposed date, very recently after you broke up with your girlfriend. She then posts this video on Facebook, where she should by all logical sense know that your ex will either see, or perhaps worse yet, hear about it.
It seems to me that your friend is either really stupid, or for whatever reason, doesn't want there to be any chance of you and your ex reestablishing a romantic relationship.
