She doesn't do much to participate or anything but she is there and kind of goes along with things which makes it all the more confusing... I think it's all an act to pacify me.
Perhaps. Of course, I do not fully know your wife and how she feels about these things. My wife loves the holidays deep down and would celebrate them were it not for these pesky Watchtower rules that she confuses with God's rules. She compensates by getting into the winter aspect of it, loves snowmen, decorated the house with snowmen and snowflakes this year (in which I left up for her after taking down the Christmas decorations), etc.. I just let her be her.
I do not care for the assemblies, boring as crap, but I will probably go to this next one since there is a hotel and a pool in it for me. I do not bother with the one day assemblies and when the district convention is in town, I do not go all three days.
Funny thing is, neither does her father and he's suppose to be a MS. People just ultimately do what they want to do and justify it to themselves in their own minds somehow.
You may not have lost your wife the way you say, but I would definitely put my foot down on some things. Our therapist calls it being assertive. Assertive anger is healthy.
