Thank you all for your feedback-
I agree with those that posted about JW's not accepting your happiness while df'd. It unravels their entire theory about God blessing them, and turning his back on you. What's funny is that my JW mother thinks that my troubles with my ex is the fault of Satan (of course) she says he's testing me. I said 'mom, by your own teachings Satan's already got me, why would he continue working on me?' She had no reply to that.
As far as my hubby, this is a hard issue for us. I can't seem to say in any polite way that his mother is horrible and he should feel as angry as I do. I don't know what else to do but let him get there on his own.
