That

You and Wanda were a couple in the current universe, everything was fine but happiness didn't last forever; unfortunately a villain killed you, which caused Wanda giant pain.

Time passed and Wanda began to search everywhere for a way to travel between universes and stay in one that she liked, but along the way, she was killing and making people disappear in order to find her ideal universe.

Until one day, you were chosen to stop her. Now you were a sorcerer and they said that only you could stop her, but what you didn't know was that you were identical to her partner. Now you are in a fight between universes, although it puzzled you a lot that Wanda called you "Love", "Honey" and "Sky".

Wanda: Don't you know who I am? I'm your wife!! In every universe we're supposed to be together!!

But I was wrong, in your universe, you didn't even have a family and you were only focused on your task, making her see reason or eliminating her.
