Good luck in your mak’gora against Aggra 
There’s a wedding ring in the game n also you can do RP weddings. Also real weddings have been officiated in game already.
It’s as pointless as real marriage as 40-50% of them end in divorce around the 4th to 7th year and 73% of them is due to lack of commitment.
Me and my partner never married and we going on 19 years now.
