Pretty sure you can't do this without using a world editing program. Just have your wife join, teleport her, and have her sleep in a bed.
You can teleport like this:
/tp [wife's username] [your username]
Using MCEdit, you can go back to your original spawn point by using "Move Spawn Point" on the hotbar and select "Goto Spawn". Then you can follow your history to try to figure out where your bed is.
If you really can't figure out, you can try the following MCEdit Filter. It will help you find your bed, but may actually take quite long (probably no less than a few minutes).
displayName = "Find beds"
inputs = (
("Search the whole world regardless of bounding box", True),
)
def perform(level, box, options):
if options["Search the whole world regardless of bounding box"]:
i = level.getAllChunkSlices()
else:
i = level.getChunkSlices(box)
print "Finding beds..."
for (chunk, slices, point) in i:
if blockExistInChunk(chunk, 26):
(x, z) = chunk.chunkPosition
print "=> Bed found near x={0}, z={1}".format(x * 16 + 8, z * 16 + 8)
print "Stopped finding beds."
def blockExistInChunk(chunk, blockId):
for a in chunk.Blocks:
for b in a:
for c in b:
if c == blockId:
return True
return False
Save the file under the filters directory in MCEdit with name findbeds.py, then go to MCEdit, use Filter on the hotbar, select Find Beds and click Filter. Now watch the console (the white on black window) and it will output the approximate coordinates of where beds are found.
Sample output:
Finding beds...
=> Bed found near x=-440, z=-600
Stopped finding beds.

All the commands are available when you type / and keep pressing Tab. It will loop through all available commands. And if you are good enough, you can figure out what a command does and how to use it by judging from its name.
You can also use the command
/help <page>. It will show you all the commands available with a simple description. You can also do/help <command>to show the specific help of a command.There's no explicit need of looking up the Minecraft Wiki every time you want to use a command unless you are really messed up and need some clarifications on the commands. I believe a quick glance of the wiki page will be enough.
