DH and I have been together over 45 years but only got married 5 years ago. We didn’t tell anyone that we were getting married not even our 7 children, who have all left home. One child found out! They found our marriage certificate. They were looking for their birth certificate and came across it. No big deal, that’s it they know. They are all fine, they know their dad and I can’t bear any fuss and weather we are married or not makes no difference to them. However our daughter in law is furious and won’t talk to us. She says we have deceived them. My son says she’ll get over it and don’t worry about her. Did we deceive them or is it no one’s business but ours?
