Will intercaste marriages work?

Yes, Some times intercaste marriages work. If They both and their families understand each other.

I think it depends upon the couple, it would be difficult for some time to adjust

It may be difficult to get family approval for inter caste marriage. But when marriage takes place, this works.

Yes, it will work as long as both the parties have love and faith in them. Though there will be problems, difficulties and issues but if the bond of love is strong enough then it could tackle anything!!! :) :)

I can't say much because as many examples i have seen they didn't work....
