Hello, friend! ^_^
Recovery or otherwise, our bodies will weigh what they weigh because that's what they need to weigh. There is absolutely no way you can sweet-talk your body into not gaining further weight unless not gaining further weight is optimal for its health and functioning, and whatever it does is not dependent upon you whatsoever. Your job is to rest and eat.
I think waiting to eat until your spouse wakes up depends on a few factors. How much earlier than them are you waking up? Are you hungry? It can't hurt to toodle down to the kitchen and grab a glass of juice and some toast while you wait for them before having your usual breakfast together. See how that feels. Sometimes taking those little measures can help us realize that maybe we've been restricting without meaning to (because ED is a sneaky devil that way).
Finally, one thing that's helped me is to stop thinking about "meals" per se. I eat when I wake up. I eat a couple hours after that, and a couple hours after that, and a couple hours after that . . . It helped break the rigidity that having certain "meals" (breakfast, lunch and supper) can create.
Pretend you're a hobbit. Wake up, have breakfast. When your spouse wakes up, have second breakfast. And elevensies.
TL;DR: the fact that you're expressing a fear of gaining more weight and waiting to eat (albeit for the very sweet reason of eating breakfast with your spouse) has me thinking that you might want to play around with things a little bit.
But give yourself a solid pat on the back. You've come a long way. Keep fighting!
