Why are men considered emotionally stronger than women?

According to your words, "men  are stronger emotionally is only because they are strong enough to  control their feelings and do not express easily, whereas women are  believed to be very sensitive by heart and thus they are unable to hide  their feelings".

A particular gender cannot be judged as emotionally stronger. It depends on a person's life experiences, lessons learned, wisdom and so many intangibles.
