Welcome AllForShow! I second what LoisLane just posted before me. Read everything you can about JW blood doctrine at JWFacts.com and then come back here and read this well developed thread about blood transfusions and the NWT here. Get your husband on board with the realisation that the lives of your children here on earth are in fact very precious and to preserve their lives is an exemption from biblical law as jesus pointed out to the pharacies while healing on the sabath day.
Take time and study/research one topic at a time and examine all facts and all viewpoints. If it is "the truth" then it can withstand any scrutiny right? You are well educated and not easily persuaded by mere opinions or twisted interpretations. Use reason, logic, and evidence to make very important decisions spiritually and elsewhere in guiding the lives of your family. College taught me a bit about the types of logical fallacies and I started noticing good use of these in watchtowers. I always doubted the blood transfusion logic they used and 1914 but it wasn't until the latest "generation" change with "new light" around 2009 that I started doing real critical research.
You acknowledge that "JW's are some of the most depressed, unhappy, arrogant, broke, pompous people I know," so don't just follow blindly anymore, take full control of your future happiness. Not All of JW's are moral/good people and it's been shown to not need any religion to be moral/good. Instill values you know YOU have and your traits of care, loving-kindness, non-prejudice, truth seeking intelectualism into your children and they will have an even bigger slice of happiness that the JW's may have so far kept you from having. Good luck and I respect your difficult and bold steps to prepare your family for the best possible life you can provide them with!
