No Offence, These are actually very creepy. Calling some random man your husband/boyfriend is weird. if someone made a wallpaper that said "Nordic_Genealogist is my girlfriend" I wil delete all my social medias.
What isnt creepy if is you are actually dating/married to a guy, and having him as your wallpaper AS LONG as you have his consent. (I remember having a wallpaper of one of the Kidz Bop kids and calling him my future husband when I was 10)
