Hello! I'm having my gf over tonight and wanted to know if I can use two steams at the same time to play the same game.

I know this normally wouldn't work but I'm part of a steam family where we have more than one copy of this game, so my question is, is it possible for her using my steam to play my game while I play the same game, using my steam, but the game from someone else's that is in the family? Thanks in advance!

Can we go through a real world example of how a Steam Family might share games?

Of course! Let's say that you are in a family with 4 members and that you own a copy of Portal 2 and a copy of Half-Life. At any time, any one member can play Portal 2 and another can play Half-Life. If two of you would like to play Portal 2 at the same time, someone else in the family will need to purchase a copy of the game. After that purchase, there are two owned copies of Portal 2 across the family and any two members can play at the same time.

In this example, if your family choose to not buy a second copy, you can play any other game in your library while waiting for your family member to finish playing your copy of Portal 2.
