Mudwing social norms about dating

Hello,

not Darkstalker posting today (we're on my second favorite topic this time !).

We all know that conventional mudwing social norms implies them sticking together between siblings starting at birth. There's also an extract about mudwings accepting other mudwings that have unfortunately lost their siblings due to the war. This is clearly portrayed as exceptional and rare as the relationship seems to be somewhat off when a non-sibling join a fraternity.

But exceptional circumstances aside, how would two mudwings would date and live together ? do they leave their fraternities ? do one joins the other's group ?

For the rare depiction of mudwing fraternities we can see that this is a strong bond and one not broken easily (queens not fighting to death with their sisters for succession). This fact makes it hard to believe that separation would be something done easily and that overtime each member of the fraternity goes away to live with their partner. On the other side i would find it surprising that one mudwing would leave their fraternity to join their partners. Maybe mudwings couple don't share a common nest ?

Has this been touched in the guide ? Because I feel like this would obviously be the type of interesting topic that would be expanding mudwing culture and develop how siblings live their lives together (shared custody maybe ?)
