wow...

So... did you just decide to ask him that, or is this something that's started happening, recently? The him not kissing back thing...

Have the two of you been acting as if you are not married and just dating?

I hear you ask that things were going along fine, but was it becoming "same old"?

As awkward as that moment might have been when you asked, what's the likelihood that maybe things can be "spiced up a notch"?

I'm just trying to figure out why you feel he's not kissing back when he used to, or you felt he used to...
