Should I text my ex?

My ex wanted to talk to me and meet up, but after a while we stopped talking, and then he wrote again, the same cycle repeated for two months. And we haven't been in contact since then, of course she has a boyfriend now but she hasn't given any indication of it. But I don't have their number or social media account. Should I contact them on TikTok? Will her boyfriend notice? My intention isn't to break up the relationship, it's to confront it 😢 This person was my boyfriend, and it's been 2 years since our last conversation (I'm writing this from a translation) I am a woman.
