Why do you want to divorce? Is your husband treating you very badly? Have you tried to talk to him? Do you have problem with your in-laws? Have you tried to talk to them or see if you can move out? A lot of things can be talked out. "又無錢,人又老,又受氣" is not the excuse for a divorce. However, "唔放心個仔,佢今年會考,又無心肌讀書,依賴性又重" is not the excuse to stay in an unhappy marriage. You need to think about what you want the most and what is bothering you the most.
