I keep losing my wife in Skyrim

I married Jenassa and I keep losing her. I went back to our house to look for her & The Drunken Huntsman's place too but I can't find her anywhere.

Solution 1:

If you don't own a house spouses tend to have a location they fallback to so if you lose them (again) check their default hangouts and they are likely there.

Solution 2:

If you want your wife to stay put, you have to own a house and tell her to live there.

You can move your wife from house to house, but once you own property you'll have a dialogue option that will tell her where to go and where to stay.
