Welcome Heartsafire! I am married to a witness wife and successfully faded. We were able to maintain our marriage. My wife didn't turn me into the elders when I was fading. I try to plant seeds but she sees through that so pretty much after my initial OMG DID YOU SEE THIS HONEY! moments when researching and learning we have an unspoken truce. Our marriage isn't perfect but it works for us, most of the time. My kids are free - so far.
Keep reading, posting and developing relationships on here because there will be days when you need a more personal friend to rant to. Good luck.
