I want to like this game so bad. On paper it is exactly the kind of game that I love, but trying to play it multi-player with my partner is just an experience in frustration. It seems so perfect for multi-player, but so much of the interface just seems setup for one player only.

This is going to end badly.

Core keeper.

It’s a co-op base building game similar to minecraft only top-down pixel art graphics. Easy to sink hundreds of hours into, and if you get yourself a copy as well, then you can both play together

Exactly this. It can absolutely be a fulfilling relationship, but it takes significantly more work than being a pair does.

It also isn’t a good fit for everyone. You have to be not only extremely confident in the existing relationship, but also secure enough in yourself to understand that your partners are going to have independent relationships with each other just like you have an independent relationship with each of them. A lot of people just struggle with that.

Personally I find it to be a very rewarding experience, but I full expect that to not be the case for most.

If it is something OP decides to engage with I would definitely recommend lots of reading on poly relationships, seeing a relationship counselor who specializes in open \ poly relationships, and visiting poly forums to talk about the potential pitfalls \rewards.

The act of talking around a mouthful of hot food.

It isn’t a terrible recommendation if you have good form and are comfortable with the lift. Deadlift hits pretty much the whole back when it’s done right, but it can also be done wrong in quite a lot of ways.

Even with deadlift, I would probably still add isolation lifts targeting the areas you want to see improvement on.

My normal routine is to combine chest back and core into one routine. I alternate that with my leg routine and accessories (mostly arms and shoulders) routine. That lets me hit each twice a week with one day off, but a lot of that is also going to depend on your personal recovery speed.

Since it’s something you would like to focus on I would recommend hitting the area 2-3 times a week if your recovery time allows.
