For two lovers,complementary and simiar personality,do u think whichone is good?

I am also with you. You may have to make many adjustments with complementary personalities. Complementary personality may be better in say arranged marriages. Marriage that happens in the most mechanical way in India perhaps- I would say even here it would be better if one could similarities rather than complementarity. However with some tolerance called from both sides may be the cpmplementary relationship gives several pragmatic advantages. You could end up rich as a couple in a complementary relationship. In a relatioship based on similarity one could have a peaceful conjugal life. I am saying it with experience. Mine is neither complementary and far far from similar. What makes it tick then is the very few places where we are able to see in the smae direction it is extreeeeemly interesting. But given a choice I would select someone who thought similarly on many fundamentals.
