Welcome,,so glad you have had second thoughts before re-investing too much back into JWism again. Glad you are going through your thorough 'checkup' process now.
Strange that your brother is so standoffish. Maybe that you never had to go through the DF process, that he is jealous? Weird, no matter.
Glad too that your dad, is having no problem doing such a thing as reporting on you. Seems to be a little more circumstances that parents are not turning on their kids that are leaving JW life and beliefs. I hope that these parents who are soon enough going into their aging processes, are realizing they need their kids no matter.
