I had a similar situation with my hubby. We disagreed on how to pay tithing or even if to pay. I felt I was less worthy because he wasn't paying it. I decided his choices didn't affect my worthiness. If I am truly doing what I think is right that is all that matters. I told him when it came to money he earned I would stand by any decision he made when it came to tithing but when it was money I earned, I would pay how I felt was right. Now no matter how much or how little my tithing is I can proudly claim to be a full tithe payer.
