I'm going to use my 'Happy' Post War AU idea for this when things are you know, normal, and Alice hasn't fallen into the post-war slump of the normal AU.
Who cooks: I'm going to say Ashley. Growing up and raising 3 sisters with her mom, she definitely knows how to cook a decent meal each time. With Alice, she knows enough to survive, but nothing fancy. If there's time or they feel like it, they might go out occasionally.
Who does the laundry and other chores: With both women being military, it's pretty standard to have a routine with assigned chores or so, and it doesn't get left behind or forgotten about. Might be a bit slow but everything always gets done.
How many children do they have: I definitely feel like Ashley would want kids later in her life, growing up with such a big family, so at least one, maybe up to three depending on how both work with parenting. Alice is iffy on it, but she's open to the idea once things are well settled down.
Who’s more dominate: Ashley is in charge of everything. But seriously, both are more dom-typed, though usually in most cases, Ashley
Favourite nonsexual activity: Probably kicking back, relaxing. I would've said a few drinks now and again but after Alice's near reintroduction to becoming a dependent alcoholic during the war, I'd say she'd stay away from alcohol. So... going to the gun range to have a bit of competitive sharp shooting.
Their favourite place to be together: Besides the Normandy, any where that they're together is their favourite.
Any traditions: Going to see Ashley's family come Christmas time. Every year, they go there Christmas eve and stay the night, and all of Ashley's sisters have their families and kids over. Most of them sleep in sleeping bags in the living room while the adults get the bedrooms. It's always a challenge to stay quiet at night...

What they do for each other on holidays: They both usually struggle until last minute and buy each other something that's more practical and useful than anything. Clothes, something they need around their home, guns, you know. Helpful things.
Where did they go for their honeymoon: Somewhere in the Carribean with white sandy beaches and bright teal water with a beach house.
Where did they first meet: Good old Eden Prime.
Any pets: They definitely have a dog of some kind, most likely a mutt or something adopted.
What do they fight over: The covers in bed, sometimes opinions on things though not often, annnnd who tops who in the bedroom. There's a reason for the bruises.
Do they go on vacations, if so where: If they have the time, they like to travel together somewhere far off and take like at least a week. Not very often, maybe once a year, but somewhere on Earth that neither has seen. (Which for Alice, besides London, Rio, and Vancouver, she hasn't seen a lot of.)
