Speak or Ghost for good?

How to condense this short story... I found out I was side hoe, took the liberty of sending screenshot sexts to the girlfriend. He asks why I did it and then I don't hear from him for 2 weeks, he apologizes to me and we kinda fall back into flirtation. I think they broke up, but I had a gut feeling to see her social media and boom and selfie or them as her profile picture.
He texted me 5 times yesterday saying the dumb "hey" "hello" "you up" why why why can't he leave me alone? She obviously did not believe me or she's that clueless and forgave him lying and just wants a ring.
I know he'll text me again. Do I ghost or say "I'm not ___" go back to her
