That is the thing. You don't marry a random person. You try to become friends. Like in RL, you don't have a conversation with a random people for over 20-30 mins at least you are forced. It is after you become friends you both then marry because you both want the items. Friends help each other. A relationship in game is rare. rp/erp is a thing that you just do cu you want to have someone to entertain you. It is obvious it won't last. But there are exceptions and mY be a few may turn into friendship (which I think it is just weird and a bad star that is IMO)or a relationship.
