comment: I'm old.  Much of my dating was before cell-phones and before texting was common in the USA.  There have always been and always will be people who overanalyze what is going on in the unknowable head of the would-be partner.  I see no difference from then and now other than the medium over which the anxiety is induced.  
  If you don't know how to make someone feel special over text then don't do it over text.  The same question would have been posed by using the telephone back in the day, or by telling a friend to tell them.  
  If you value setting aside time then do it!  Just don't think that people were good at this in the past!  They weren't.  This is the stuff of shakespeare, let alone sms.
