After marrying Ysolda from whiterun we went to the temple and got married unfortunately she left after and disappeared and I can't find her at her house or anywhere in the game please help me as you may know you can't re marry in this game

It's a bug. If you don't talk to your new spouse immediately in the temple about living arrangements sometimes they just disappear once they leave. Hope you have a savegame you can go back to.

If not, you can always roleplay that you were cheating on your wife and were caught so she left your sorry ass right after the wedding. And because you were dumb enough not to sign a prenup you now you have to pay her 50% of what you own.

This happened to me with Borghak. I waited for 24 hours and she came back inside the temple.

Use uesp to get the id for the Mrs. then open the console and type player.moveto id

She's with me, sorry man.

I had to do my ceremony 3 times before I could catch my husband.
