exactly. to my knowledge, dating is not just a tool for finding a mate for marriage in the west. its a cultural and social norm, which starts in their teens for boys and girls here, with no strings attached until things are taken to the next level with mutual approval, with no promises of a commitment either. it is thus very different from the new-found dating concept in our culture where a lot of times, dating comes as a result of a serious interest and with the intent to potentially make it into a long term commitment, talking about the majority of adults here, in teens its still considered unaccaptable since dating is seen strictly as a rishta seeking process.
no doubt a person is scum if they take advantage of a girl by misleading her with wrong intentions but I see gora men doing it all the time too so its unfair to blame the majority of desi guys for doing it. dating is a very dodgy business especially for girls, unfortunately they have a lot more on the line then men do so caution is key by choosing their partners wisely, after all responsibilty in these relationships is mutually shared.
