What about the teachers? Don't they have a personal life?

Hey all!

I'm a new member of the group, and so forgive me if this topic has
already been well-covered. But, especially if you have come to a conclusion, 
please tell me about it (well, write me abut it would have been a better 
line).

I'm also really young, almost 15, and a Romanian citizen, but I have read 
all the  Harry Potter books in English and I really adored them. Anyway, 
please excuse any of my language mistakes.

My question is: Do the teachers in Hogwarts lack a personal life? As written 
in Order of the Phoenix, Professor Trelawney was intented to be kicked out 
of Hogwarts by Umbridge. So, she used to live there. Like all the other 
teachers. In this case they couldn't have had a personal life, a family or 
anything a normal human-being (either muggle or witch) usually has. Do they 
have to devote their entire life to teaching at Hogwarts? Until they become a 
teacher, do they have friends, can they married? In that case, when they 
become a teacher, they just stop living with their husaband/wife?
And another one: are there things like divorce in the wizarding world?
