.i’m sorry i know you are all going through a lot today because of this celebration but i don’t know anyone else to ask
No need to apologise, were not going through a lot, we actually enjoy talking about it with each other now that we're out of it.
As a previous poster has said, you were excluded because he doesn't want to have to bring you up. Also, he'd likely be embarrassed you being around because JW family's look down on non JWs. Sometimes in a married couple one will join the religion and JWs won't look at the non-JW with the same respect. The non-JW is only viewed as a potential convert at best.
If he's acting this way now it's a very bad sign. He's obviously still got some remnants of the cult brainwashing going on in his mind. His family will be using passive aggression to lure back to the cult and, as a result, away from you.
In situations like this their literature portrays YOU as the problem and him as the "good JW returning to "the truth".
