Vijay your friend says: she doesn't have any match for her within the Jat community??????????????
If she has any excuse or any thing else and she wants to go for marriage outside the community then it is fine. But she should not say that she has no match within the community. It appears that her social circle or knowledge about JAT community is limited and you(VIJAY) should help her in that field.
There are people who want to go for marriage outside the community because they love someone, there is no harm in doing so. I will say always go for your love but do not find excuses to justify it before parents that there are no matches available within community.
