The finality was a bit of a miscommunication.

I will initiate texting. I will not repeatedly initiate texting. i.e., if I don't hear from you unless I text you first, in all circumstances, then I'm going to text you less. I don't want to be the one who is reaching out 100% of the time. I am willing to initate texting first even like let's say 70% of the time but I need the guy to reach out to me of his own volition at times. Otherwise it doesn't feel like he is interested. So I moderate my texting in response to how other people text me, but I don't unilaterally not text. I observe whether I am extending myself way more than the other person, and if I am, I scale back.

I totally believe in the middle zone. When I stop initiating text conversation with a given person I am giving that person the opportunity to meet me in the middle and seeing how long it takes.

Same with multiple texts - I won't text a person if they don't respond after, generally, two texts. Either they are busy or they are ignoring me and in either case it's reasonable not to text until I get a response.
