Do I have the right to respond to negative posts about me from my ex?

My ex occasionally posts videos about me on her TikTok. Which is crazy, because we have been broken up for 2 years now, she has a long term relationship, even longer than ours was and yet she still posts stuff about me sometimes. She does post them on her somewhat more private account that only I and maybe a few others know about, but I still see them, and she knows I’ve seen them. I don’t say a word, I don’t leave a comment, I just want her to know I seen it so I leave account views on. I have literally not even said a word to her since I left her in 2022. At the time I left her I was just turning 17 and she was 16. The topic of her videos are not necessarily in poor taste, she doesn’t get very petty or rude, she simply just makes videos about things I did that “traumatized” her for lack of a better word. The thing is though, the stuff she is saying is not even true. It’s not like anyone knows who she’s referring to because it’s all randoms who see her videos, but she’s not even being truthful in the videos. I honestly really don’t care what she says about me, unless it’s super horrific and untrue of course, but I am fighting myself so hard not to say anything just to see what would happen. She has a deep hatred for me and might fear me maybe? I feel really nothing towards her which is why I don’t ever say anything. I am not mad or upset but she feels hurt clearly, so would I be wrong to try and invalidate her feelings towards me? Again, I really don’t care about the videos, she can post one everyday if it’s what her heart desires, I just want to see how she’d react if I actually said anything, and if I would be out of line or weird to do so.
