say something to her parents like "oh, you daughter is so nice and pretty, but he did not feel a spark with her".
This is the best thing to do but still most desi parents wouldn't have the guts to say it..
Say that everyone has their own requirements and wishes for what their spouse should be like. The guy doesn't want to rush and would like to look at other girls. The girl should also continue to look at other guys.
i actually really like this excuse! If a family was to say this to me, personally, I would appreciate that! lol
