I don't know why everyone expects him to call. yes she could stand her ground, but if he's thinking exactly the same thing, then neither of them will and it could all end over the simple fact that they just need some straight talking and both of them were too proud to do anything about it.
of course he could be finishing it, but if he wanted her to move it, unless he's having 2nd thoughts, that might not be the case.
I would suggest she drop him a line and ask if he's having second thoughts. if he is then take it from there. and if he's not, they can thrash out what they need to, to avoid anyone being walked over like a doormat and thus live in domestic bliss.
it's a huge culture shock for both parties going from being single to co-habiting and each person has to adjust to the others habits.
