Couples moving in together has become so common and especially among campus couples. The common reason girls give for moving in with the boyfriend is that they want to cut the house rent and bills.
I asked a guy (not a so close friend) why he moved in with his girlfriend and his reasons were somewhat annoying. First, he claimed that he can have the chick anytime he wants; he clearly meant sex. He said that he didn’t have to go all the way to where she lives to ‘get it’.
