I am in your shoes. An inactive LDS woman with an inactive family. Long story.
But if you want to go back, it's very easy. Just go back. Where are your church records? Do you have a visiting and home teacher?
If not, go online to find the nearest church. Check out
www.lds.orgAlso you can call the local church to find out the meeting time. Believe me, if you return just once, they'll fellowship you back into the fold. Everyone will be very warm and welcoming.
That has been my experience. We're still considered inactive for different reasons. Still seeking. You may have to return without your husband for now.
Best wishes to you. I'm happy you have the faith and courage to do the right thing.
