They could very well be married, but we just never hear about their spouses. The only real important professors were Dumbledore, McGonagall, Snape and the DADA proffs each year. I actually rather like to imagine that there's a Mrs. Flitwick out there as cute as her professor husband who always fusses over his robes. It's clear that Snape never got over Lily and he also had very little time for romance, what with being a triple agent and all. And, as stated, Dumbledore was gay, which explains why he wasn't married. I think McGonagall would be a little picky about her life mate. Perhaps no one was ever smart enough for her.
As for the DADA teachers, we have Quirrell, whose main romantic relationship was with a face in the back of his skull. Then there's Lockhart, who was so deeply in 愛 with himself, there wasn't any room in his ハート, 心 for anyone else. Following Lockhart, we have Lupin, who as we later learn does, in fact, get married. After Lupin, there's Crouch (or Moody), neither of which were married because Crouch was legally dead, and Moody is kind of married to his work. After Crouch/Moody, there was Umbridge, who, let's face it, NO ONE WOULD EVER want to marry for ANY REASON. After Umbridge, there was the unforgettable Slughorn, who was a bit of a hedonist, and therefore I doubt he believed much in the institution of marriage, but I'm sure he had his fair share of flings in his day.
Still, I do believe strongly in Mrs. Flitwick. And perhaps there's also a Mr. Sprout out there too, studying the botanical anomalies of mandrakes in South America. ;)
M.. im agree with ya,i always think that Dumbledore is with McGonagall xDD.. または will be with her.But then Dumbledore die .. :/ And this is really sad,that everyone of the teachers is alone and dont get married of any of the books.
They could get married of course. They have a choice! And J.K. Rowling says that Neville becomes married to Hannah Abbot I think and he's the new Herbology teacher at Hogwarts. So any of them could be married.
hmmm. well this is the way i think of it, when trelawny(sp?) was being sacked によって umbridge she 発言しました "i've been here for 16 years, hogwarts is my home" im guessing that this means that the teachers lived at hogwarts, which would make it very hard to have a family considering that they would never get to see them. teachers even stayed at the school durring break, except in book 4,i believe either pro. sprout または flitwick mentioned something about going to their sister over the winter holidays. but nothing about any spouces.
