Enemy Territory is a great game for having some alone time sniping each other.

It doesn't sound like the types of game you normally play but I've had fun having an online date or two with it :)

I've put dozens of hours into Stardew Valley with my girlfriend. You can help each other out in pretty much every aspect of the game, but can also play independantly from each other. If you're going to play split-screen, I recommend getting a second monitor; we found it more fun not to be able to see what the other player was doing right now.

Overcooked is a fun, hectic cooperative game, although it can be rather stressful. Depending on the people playing it, it can either be an amazing experience working together, or they end up yelling at each other because things are just too chaotic and not going the way they want.

Some coordination and teamwork is needed, like any couple at home.
