Things that would raise my hackles in other sitches don't in Dia's sitch, because the past seems pretty murky,meaning, plenty of faults and infidelities to go around. And if it takes one person a little bit longer to pull his head out of the rabbit hole, well, that's not entirely unreasonable. Plus, the movement in their general relationship dynamic seems so very very positive and not like standard cake-eating somehow.
Dia, I would do what the spirit moves you to do, erring on the side of love, compassion, and generosity *at least* until after The Talk. Then, when at least you have some mutual agreement on what the level of committment to the marriage is, you can worry about division of labor and other boundaries then.
Stay the course, girlie. If anything were to go pear-shaped now, you'd be hurt badly. That's a fact; accept it. Don't let your nerves cause *you* to pull away against your overall intention.
