I am not married but I would use it for "dear heart" when reffering to my signifigant other.
“Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.“
Mine would be Dear Husband! Or you could use:
Well....I am a Cat person!
"A truly happy person is one who can enjoy the scenery on a detour."
