I've been acting like I am totally unaffected whenever around my cheating ex (same social circle) and chatting up people, hitting on girls, etc. She even told our friends that I'm over it and she isn't. She messages me you don't give two shits and I'm losing my shit over this. One day after seeing her with the dude she cheated with I lost composure and broke down in front of my family (terrible mistake I know). They took it upon themselves to text her to back off behind my back. She messages me saying you could have talked to me yourself etc (even after family told her not to tell me, lol). She obviously loved knowing she is affecting me.

I have been going no contact for so long. I don't reply to her anymore. Should I reply now and try to salvage this by saying I have no idea why they even talked to you, I haven't even mentioned you? If she doesn't buy that I can say something like they only asked if you were at our outings and I said yes. Or should I just forget about it and stay no contact?
