First off, WELCOME to our group of very diversified ex-jws (and others).
You sound like a young lady that overcomes obstacles, even though you have to do it through hardship and heartache.
You have good news in this story (congrats on the wedding!) and bad news (shunning from your family). Sounds like you've dealt with their shunning and abuse before, so you can deal with it again. Focus on the good, dear, and let the cultists have their cult. Any children you may have may actually be better off, imo, not being exposed to their nonsense and lack of real love...... Journey-on!
