If you feel like you simply have to acknowledge receipt of a payment for documentation, then make it as businessy and impersonal as possible. I also suggest email instead of text.
"Received your transfer of $14.99 on 11/01/2018. It was applied towards the $188.54 Visa bill for the month of November 2018."
Don't engage in anything more than that. He could very well say ”Happy New Year” or "Thanks, I hope you're doing good." My XW tried that, but in my mind my return address was always no-reply@joe2017.com.
Well, that's the "easy" thing about my sitch I guess. H doesn't ever try to do any temp checking, at least not up to this point. He's very much got the "business only" thing down from his side so that makes it a lot easier for me to follow suit.
In this case I won't even bother with any response then to the transfer. I didn't for the other ones either, so will just keep on keepin' on.
I hope one day I do have a chance to respond to a temp check. Temp checks, while just temp checks, are technically a good sign, right? I'm kinda sad that people talk about their spouses temp checking and that's never happened with my H I know I do need to be prepared for if/when it comes though so that I don't get too excited and do the wrong thing.
