You have to save them as doc in a game first. This means that the only way to marry your alt is to multiaccount and cheat.
I won't rest until EVERYONE can marry who they want to. It's ridiculous that it's 2016, almost 2017, and you're not able to marry yourself.
We need change.
mayb i wanna marry my main
Make an alt,switch to the alt propose marriage to the main account,switch back to main and accept it.
