I'm happy for you!! It's amazing (yet sad) that when we pull away, that's when we're actually our most attractive, isn't it?
Not to be a buzzkiller or anything, but I do hope you'll consider getting a full-panel STD test if you haven't already done so, just for your own peace-of-mind. There are too many horror stories (including on this very board) of STDs (or worse) getting passed from a formerly wayward spouse to their mate.
I'm also curious as to what boundaries, if any, you and your husband discussed in conjunction with getting back together? Did he agree to be transparent?
