I lost my wedding rings and I haven't told my husband.
Why wouldn't you tell your husband?
I am afraid he will be very angry with me.
While it will probably upset him, it is important to talk with your partner about things. It will help your relationship become stronger than if you hide things from them.
Why do I have to tell the truth? I can just buy another one and say nothing happened.
What if he finds out it's not the original ring though? You should just tell him, I'm sure he'll be understanding.
