Why do ppl say opposites are best....

Re: Why do ppl say opposites are best…

but you would probably only need for your partner to be flexible in some things in order for it to work but in terms of beliefs and culture, interests…like say if you wanted to go to the eid get together but your hubby is an introvert plus he hates social occasions, doesn’t like celebrating anything would you still want him to be opposite to most of what you are?
