Two cents from a Nepali woman... no need for caste revelation here.

Well if a man treats his woman with respect and fulfills her need, any woman would stick with her man till death do them apart. However if a man is going to consumed with his libido, his inefficiency and his roving eyes... yes he will definitely lose her to another man -- maybe even a different caste or even different nationalities. Fulfill our intimate/biological needs and nurture us emotionally and we will do the same for you. Boys.... times are changing so it imminent that you move with the flow. Hope this helps.
