A certain type of woman and older man

Sorry, but I don't quite understand your thought process here. Perhaps you can help me?
You say "I felt a little like I was being used by this woman, but we were using each other with no false expectations or promises, so that is ok with me..."
Seems to me that you are 'using' her for your benefit - so why should you feel she's using you? Tit for tat -check mate.
Then you comment that "The rest of the texters are just playing text games. Life must be pretty dull if this is the method they use to "develop" relationships."
Pero aren't you a "texter" also? Just a male "texter' rather than a female...what's the diff? So it would seem to me that it is also your life that is "pretty dull"if you are doing the exact same thing the females you are complaining about are doing. Perhaps I am mis-reading your words?
