I am a person who prefers texts over calls.
Are you talking about sending long texts on a phone?
If that is so, even though I don't know if you're boring or not, I can assure that I would not read it. I never read/reply to a large text I receive on my phone (ok, maybe I would read it if it was from my spouse, but she can reach me much more efficiently using other means).
I find the screen of any phone way too cramped, and the font way too small, for any kind of long form reading. Plus, the text layout will be shitty at best.
Imvho, typing long texts on a tiny virtual keyboard is like trying to do brain surgery wearing mittens while riding a roller coaster. And reading it would be something like eating soup with a fork ;)
Obviously, that's just my personal opinion, anyone is more than welcome to disagree, but this may help explain, partly at least, the lack of reaction to your long texts? I mean, people simply do not bother reading wall of texts and/or they don't feel like writing their own wall of text on such a poorly adapted keyboard/screen combo?
As an experiment, you could try writing much shorter prose and see if you get more reactions from sending those?
