yeah i don't get unhealthy relationship vibes from this? we dont see them talk out a lot of things bc they rarely actually take issue to things that occur, like i think the only potential conflict they've had prior to this was the mixer, and ritsuko hasn't been on any since then. if shed been going regularly and shuichi never brought it up it'd be a cause for concern, but they're feelings were actually in sync on that so it never really got to the point of needing a discussion. the dead bedroom is the first real issue that's been broached, and its one thats fairly typical for a long term relationship, furthermore its clear that they both care for each other, so im p sure they'll work it out
