exclusive

friend in a long distance relationship tells me his girl told him it's okay for him to go out on dates here...

me:  'aw!  be careful about such permissions...  it could cut both ways...  it might mean she, too, could go out on dates over there...'

friend:  'it's also okay with me...'

me:  'oh!  it doesn't work that way with me...  i want my boyfriend exclusively mine...  he's not allowed to date other girls!'
