He may not admit it, and may not even know it, but odds are your husband likes being romanced.
I explain romance to men as doing things that show you are thinking about your spouse while the two of you are apart. The planning show intent and thought, and knowing what your spouse enjoys show you are paying attention. As you are probably more aware of what he does and likes than he is with you, you have a distinct advantage on this one. Give it a go, you will bless him, and you might inspire him to reciprocate!
Wishing you a happy Valentine’s Day!
~ Paul, I’m XY and I like it when my wife is romantic.
