Its very complicated these days,
A month of knowing each other or a week can work for some,
While some keep having sex for years with other but they aren't partners because its just sex and no emotional connection.
I'm a bit old school and in my opinion its a relationship when the two individuals are exclusively interested in each other, loyal to each other and genuinely attracted to each other as individuals rather than just sexually.

You should always start dating a person that you want a a long relationship with. It should always be a relationship.
