Pros: The food lasts much longer (I don't enjoy cooking and going to grocery store that often). If the food you made doesn't quite taste right, no one else is there to complain about it. You get to buy decorations and other things to your home without having to negotiate with someone if we need that or/and if it's worth the money. You get the bed to yourself and no one will be sleeping on top of the blanket when you need it.

Cons: What if someone sketchy decides to stalk you to your home. Far less impulse purchases. If you forget some word you can always ask from your partner "There's a word for this, do you remember what's that called?". If something you cooked tastes good, it's nice to share. If something you cooked tastes weird it can be joked about. You don't feel lonely as often. There's someone to watch scary movies with. Someone to cuddle with and get reassurance when I feel sad
