Okay...taking it further...check the temperature by perhaps you are both in the kitchen, touch her hand, brush by her, small intimate gestures. You don't need hugging, massaging, kissing, hell sometimes laughter is intimate. A shared joke between the two of you. A smile shared.
The warmth needs to be rebuilt between the two of you. She may feel that intimacy from you may be as simple as taking out the trash, picking up the kids, easing the burden of chores, etc...test the waters and see what gets you the results that you are looking for. Just like DBing, right?
