Good night texts stop
My advice is if it stops well that is all that has happened – it has stopped! Do not re-visit every conversation or text with that person to see if you have done something wrong. The good night texts stopped because the other person stopped writing and sending them.
The best thing is put out a text are you okay if you want – but then do everything in your power to leave them alone. And no they cannot just text you next week all of a sudden when it suits them and you start where you left off. Ask for an explanation and if you are happy with that – maybe give them another chance! Be brutal – our time is precious.
