The thing with no contact and no texting is to stop and ask yourself what the point is
This of course only applies to exes in any form be it exbf exh exfwb.. btw.
If your brain manages to come up with some twisted reason for the contact, that you've convinced yourself is reasonable, try to unravel it. Post it here. If you don't want to post the reason here chances are you already know deep down that it's daft and pointless.
Like with BC... what is the point in me contacting him? Even though we didn't fall out, he did nothing wrong, he didn't treat me badly, there's still no point. There is seriously none. All it would do is spark a conversation that would remind me how well we get on and that he is a 12 hour plane journey away. I'd feel like shit. I don't want to feel like shit, I'm into self preservation rather than destruction.
What about the ex of the famed big bad break up? If I contacted him now I'd look sad and desperate. He made his choice and is clearly happy with it. So again, no point. I could tell myself I need closure, I could tell myself it's been ages now so I want to see how he is doing, but even if he did reply it would only confirm how happy he is with his choice, it would pick the scab and be pointless.
What about exes that contact me just saying hi? I don't reply to them either, otherwise I'm just feeding their ego, or giving them false hope... delete as applicable. There's no point replying just to be friendly or because 'I'm a nice person' you can be a nice person and still ignore people who serve no purpose in your life.
And, thinking of the above, I wouldn't want to text an ex of any kind and have them reply just to be friendly, or feed my ego, and/or result in giving me false hope.
So really truly ask yourself what the point is and what exactly you hope the outcome will be.
and as I say if you would hesitate to post it here, chances are you already know you are being daft.
