As a married woman you aint supposed to be airing your marital life on a public forum,when the book said two shall become one, that goes deeper than what people read, two shall become "one" also implies that any issues that you and your husband have should be resolve between both of you,both of you which is the same as one,you dont take "one"s issues to two or three parties,  if u dig what I mean, not telling your daddy, mammy, friends,naijapals etc.And theres a reason why you dont take it "one" issues to two or three parties, it creates division among "one"
