Is there an easy way to just get rid of it? Or preferably, only make it possible when the colony has a minimum amount of citizens?
Just curious: why? More couples = fewer bedrooms.
I made a scenario where I build me and my girlfriend with prepare carefully and I broke up with her after she proposed to me (in the game ;) ). Both of these things don't make any sense under the circumstances of crashing on a unknown world, and as we're playing in commitment mode, I had to close the game with task manager so it didn't save.
