B, you might apologize sincerely for misplacing her things. Do your collecting and sorting at night when she is asleep. Keep the collections in sorted boxes for when things goes missing, again. Order socks in the same--her favorite color. Play more of her favorite music (and take the Buspirone yourself when you need it--the only thing I'm joking about.) Try to remember all of her favorite things, comb her hair and massage her shoulders, charm her the way you did when you were courting. Always be on her side; there won't be any scenes.
Bless you both.
