Everyone's given such excellent advice.Please listen!
Only one point I want to reinterate - the guilt this woman feels is such an intrinsic part of her involvement with this toxic religion that it's inseparable from her present emotional disposition. You don't want to subject yourself and your (poor) children to that - not knowingly at least - so now you DO know. Don't only take two steps back - turn and run the other direction!
I'm telling you friend, the JW religion can ruin any good woman - and she wants to go back, lead by her guilt. I'm sorry you feel so drawn to her, and I'm sure it feels like true love - but "it's better to have loved and lost, than never to have loved at all." This is a lose/lose situation for you and your family. Better that you stay away and work on your marriage now, than look back some months or years down the road and wish you'd never heard of the WatchTower and it's psychosis-driven, mind-controling, guilt inducing, twisted, warped and absolutely poisonous theology. She has already demonstrated what a powerful influence it has on her - please take that as a huge HINT of what lies ahead if you proceed to listen with only your emotional heart. If she were to become involved with you on a personal level, she must try to recruit you and your children into 'The Truth', or she wouldn't be a good little(brain-washed) witness.
Listen to the sound reasonings of your mind - use your brain, man, and just do the right thing - you know what it is. It may be difficult, but you'll have no regrets over making what would be an 'improper', damaging and life-altering decision. No matter what it is you feel you want, forget yourself and do the right thing by your wife and children. If it doesn't work out, you'll at least know that you stood up for what's right and did everything possible within your power. Then, IF she leaves that religion - which is a psychological and emotional turmoil in itself - then you'll be free to move on with your next life phase. I just hope, for your sake and your kids' sake, that it doesn't involve the wacky watchtower... OK now, rant over...
May you find peace of mind.
