Hi Jen,
Your parents will be wishy washy on how they treat you because the WTBTS is dishonest about it. In the literature, the WTBTS walks right up to telling parents that their DF'd children are dead to them, but doesn't actually come right out and say that. The WTBTS is sneaky and they fill in the blanks in talks and comments from the platform. Then later when someone says "You teach that parents are to treat DF'd children as if they are dead" the WTBTS claims innocence and says "We didn't SAY that (in the publications)". But, they are lying because they did say it in public talks either in the congregations or at assemblies.
Then, every once in a while when public exposure on this issue becomes too much, they will publish a "let them return to Jehovah...." article that they don't really mean. They won't actuallly follow up on it. So the family of DF'd people will soften their hearts a little until the next "Are you keeping the congregation clean...." nonsense.
It is a cruel game that the WTBTS plays.
Your parents are just caught up in an emotional roller coaster.
What I don't get is how they use your children as pawns in this.
If it were me I would tell my parents, "if you want my children in your life then they have to be all the way in your life or they are not in your life".
Someone on here made a great post the other day about telling his family words to that effect. I don't remember it exactly now. That way you can put the burden on them and take it off your own shoulders. You didn't do anything wrong.
I'm sorry you are going through this.
