How long does it take someone to accept a friend request on Facebook?

[Theresa]

I created a new Facebook account, to find my ex's name on there. He has changed his name. I searched his name, & everybody else with the same name, came up in the search list. Only thing is, I saw a page with the name & no profile picture or any other pictures, let alone, not even a lot of info on the page. So I requested to be friends, jus to see "supposedly", if this might be my ex. This is why I asked how long does it take for someone to accept a friend request. I don't have a lot of info or profile pics on my new account either.
