I fully understand. In my case, we did not break up but she told me she wasn’t sure. Then I initiated NC for a week and ignored all her messages until she texted me “I don’t need this shit, if you’re not answering we can end things right now” so we agreed to talk and she was really pissed. And a couple of days later, she really did end things. So I am not sure if NC while being still together is such a good idea generally. But on the other hand, being nice to her didn’t help either the weeks before that. Maybe I shouldn’t have stopped with NC back then at all. It’s very difficult to say. I’d love to hear another opinion on this one. I have no idea what you should do honestly because I compare it to my case and am not sure either, if it was good or not.
