i have to highlight that for marriage counselling to work, BOTH parties must be willing to seek help.
if one is dragged by the others to go for it.... its kinda wasting money.
at the very least, explain how marriage counselling may help and convince the other party it is worth a try.
i have not gone through but seen other couples who went through. as long as one is dragged into it, it may be a terrible waste of time.
