清官难判家务事
Sometimes it's difficult to judge when we only listen to one side of the story. The girl's story sounds sad but then again I feel the man just being too "stingy" or too "calculative". Being an old man marrying a young bride, he kind of feel not so "secure", lack of confidence and scare that his young wife will give him a "green" hat.
Other than dat, he is not dat "bad". We have heard much worse stories. Don't encourage her to divorce him la, I am sure there are better solutions than just divorce.
just my 2 dong worth for the day
