So I parted ways with her in a forest after she helped me kill some bandits.

I never saw her again for months.

Then I defeated Alduin, crafted me some Daedric daggers, and when I enter the Drunken Huntsman (yeah, I married her), there she is, asking me how I am etc.

has the store made any money?
Yeah, 10800 gold love.

LOL!!

So at a 100 gold a day, that's like....three and a half months of in game time.

Where was she all this time? I have no idea.
I did think of searching for her once but didnt know where to start.

The funny thing is, that she couldnt have bugged in some temple or something. She was outside, in an open area. I left her there, and I walked back with her a little bit, but then I ran way off ahead on some quest.
Her return seems to have been triggered by me completing the main questline, or perhaps the war, as I finished both probably within a few game days of each other.
But I cant imagine what was holding her up.

Funny though.

Although now I'm feeling guilty about having feelings for the female Dark Brotherhood Initiate.
And how do I explain why I sold our wedding rings?

Jenassa's more than capable of taking care of herself, it seems!

And don't tell her. Buy a gold ring, throw some cheap enchantment from her and tell her it's your wedding ring. No one will ever know ...

Flip it on her for abandonment and tell her She hurt you. Thar's why you sold her ring fell in love and became a polygamist so now it's threesome time.

Lol xD.
