Be a little aware before you are trapped! Marriage is a trap: you will be trapped by the woman and the woman will be trapped by you. It is a mutual trap. And then legally you are allowed to torture each other forever.
Worst, when this sensualism intrudes into the education of young women, and withers the hope and affection of human nature, by teaching that marriage signifies nothing but a housewife's thrift, and that woman's life has no other aim.
To speak frankly, I am not in favour of long engagements. They give people the opportunity of finding out each other's character before marriage, which I think is never advisable.
