This story takes place in a universe where it is not forbidden for the Jedi to love and raise a family. However, Jedi should only look for partners among each other, because the normal people don't have the Force as a protection when the Jedi is on missions and therefore Yoda's famous sentence applies again (as seen further on in EP II - because Qui-Gon doesn't die and the Jedi meet a Sith much earlier) "Fear leads to anger, anger leads to hate. Hate leads to suffering."
