So here how it goes, the person who answers my statement, will do another statement starting 'what would you do if....' and the person that posts after him answers the question and does another of those statements.

What would you do if you marry someone in the game and when you're taking a stroll with him/her appears a dragon?

Tell her to get the F* out from there unless I've noticed she can take care of herself in a tough combat situation. If she'd be good in combat I'd say "what do you say we take a leap of faith" with a smile on my face, engaging the dragon in a battle worthy of song with my wife by my side.

If it's possible, tell them to run back to the house, would be Elmfrid's choice.

Rymariel might get married, either to another High Elf, or an Imperial. ;] She would get them to protect her as she flings spells.

And Dar'Nima has no time for marriage, she rathers to go it alone.

Forum games are not allowed. I think?

You are correct.
