In my opinion I don't think its a good idea to "force" her to stop attending by not helping her.
Sirona, while I agree in principal I do feel that the majority of JWs NEED some sort of emotional crutch. If she said ''I can't attend meetings because Mr Scotsman won't come with me'' then it's a joke. He isn't physically stopping her, he's made HIS choice, not hers. JWs believe that the World should make allowances for them (especially in divided families, it's ALWAYS the wishes/beliefs of the JWs that can't be offended). Does she care about Scotsman's beliefs?...nope, we all know that JWs have ZERO respect for others' beliefs...maybe if she does manage to go alone, she'll see JUST how loving they are if she hasn't a husband in tow.
