For a start, you’re an unusual burgher wife - most of the crusaders on the Fourth Crusade were French. If he writes back, then probably within a few months (letter travel time) of him getting up to all the shit he has been in Constantinople (although not very many Westerners mentioned the whole looting and pillaging of the city thing). If he doesn’t, then you find out via rumours - which could literally be anything. Everybody was pretty pleased initially, but opinions went south after it became clear that the crusader states in Greece weren’t viable. People were generally pleased that the East-West Schism had been healed, and the Pope was publicly supportive. You’re probably still pretty pleased though, since your husband got given redemption for his sins, which often also covered spouses, and you had some pretty mad tax breaks while he was away and then for a bit after he got back.
