What also gets me is just how weak it is. This appeal to emotion is little more than, "Come back! .... We need you! .... Come back!" There isn't anything there. There is no substance. It is an attempt at emotional extortion but that is on them. I'm not the one doing that, that's them. Geez.
I perfectly understand that. If your family are acting the way my family did, I could suggest that the "weak" texts and communication may not seem so lame to them. If you notice, they are designed (ok, designed may not be the right word), they are intended to tell you something but not for you to reply anything other than "leave me the eff alone". They are not invitations to conversations or dialog they know well they themselves don't want to have for the simple reason that you are right and they are wrong.
So if you look at them from than point of view, their lame messages serve their purpose, which is to do their job as JWs to reach out to you at the same time they remain detached and not hear anything you want to say. Also, if you reply at all, it should be either taking a stand, which gives the the perfect excuse to solve their problem, or just show up and "come back". Notice to any decent person with basic manners those seem to be the only viable options with that type of communication. Either way, they are definitely not about you.
