Drama, drama

So I had a falling out with my best friend of 10 years almost a year ago. If not longer than that lol. Today I found out she posted about me on her TikTok gloating that’s she’s doing so much better without me in her life. I have never once gloated about my life being better without her, even tho it is. I’m just super bothered by this. Do I stoop to her level & let her know I seen the videos? Or do I just pretend to be blind & act like she’s not talking shit about me? Just kinda dumbfounded by this whole situation because I have reached out to her since the whole situation and checked in when I didn’t even have to, I was just being nice. I hate drama but it seems like she gets a rise outta causing it!
