My ex started posting video with me after the breakup

Hi everyone, my ex gf dumped me more then a month and a half ago. We are no contact since that day....she texted me last monday just to ask me a stupid question without even saying Hi to me to which I did not reply. After some days without checking it, I checked her tik tok profile and I saw that she started posting videos of our travels we did this summer. In basically all these videos there are clips of me or of me and her laughing or smiling. I really don't understand why she is doing that, is very strange also because she blocked me everywhere except for whatsapp. I mean, all the travels we did were really beautiful and posting that makes completely sense, but I dont understand why choosing also clips with me. I don't know
