Differences in a relation between now and the 18th century

During the last 300 years the relation between a boy and a girl has changed a lot. The first thing that has changed is how they meet. In the 18^th they met in a party, normally the parents were near and with a lot of people watching what they do. In 18^th if you want to talk alone with a girl you have to dance with her( in my opinion have a conversation while you are dancing like the film is very difficult) and obviously You couldn't kiss her in the first date. Nowadays the first contact with a girl is using a internet or in a disco, the second option is better if you don't like to talk because in this places the people only want to dance. Then when you decided to have the first date (ALONE) they always go to a romantic place and they kiss and sometimes more...

Summing up, In the past if you began a relation is because you love the girl and you wanted to stay with her all you live. However now when you began a relation normally is for some months, often some years but only sometimes for all the life.
