Hi bsand20, You have done nothing wrong. You love JWs unconditionally. You can only control your actions. You cannot control other peoples' actions. If you are thinking about going to a counselor, do it sooner verses later, especially a cult-exit counselor. You can ask for a recommendation for a cult-exit counselor in your area through www.freedomofmind.com or talk by phone with Steve Hassan or another counselor to address your unique issues.
Have you read any of Steve Hassan's books (i.e., "Combatting Cult Mind Control", "Releasing the Bonds: Empowering People to Think for Themselves", and (his latest book) "Freedom of Mind: Helping Loved Ones Leave Controlling People, Cults and Beliefs")? If not, you should to improve communications with JW friends and relatives. When JWs shun you, have you thought about saying, "Shunning me only proves to me more and more that JW.org is a dangerous cult. I will never return, so why waste time shunning me when we can talk instead?"
Instead of arguing with JWs, have you thought about asking them questions? How would they respond to you asking them on Facebook, "Can you disprove [name of a specific article] on www.jwfacts.com? the point is to turn the tables on JWs and let them do the work to disprove your beliefs. They can count the time and you do not have to argue with them.
Peace be with you and everyone, who you love,
