Yes, the DOUBLE DARE! Actually, my H gave me this idea. He told me that before the A, he'd gotten in the frame of mind that he doubted my love for him and was looking for evidence that I didn't.
Now, he realizes that I did all along, and is noticing all the WAYS that I show it.
ILY's are great, but I bet if you look for all the little things your W's DO that SHOW love, you will find more than you think.
