My gf broke up with me and she keeps reposting stuff about me

So im short, my Gf (F18) broke up with me cause our relationship was beginning to become exhausting, A reasonable thing it took a while but I got over her and took alot from that relationship, were still friends however, its obvious she hasn't moved on.

I tend to see her reposts on my FYP on tiktok and they still are along the lines off "I loved you and let you go" or "I did this for my sake" Keep in mind she broke up with me nearly two weeks ago.

I understand people take loss differently it wasnt easy for me to move on but I pulled through, and the frustrating part is that when I try to talk to her about it, she Gas lights me swearing they arent targeted at our old relationship.

Im really considering cutting her off completely as im slowly realising maybe she isnt so good of a person
