How long do you date, before becoming boyfriend/girlfriend? Before becoming exclusive? Before you say I love you? Before you have ralations (sex)? Before getting engaged and married?  What's that old saying . . . . . why buy the cow if the milk is free ? or was it don't cry over spilled milk . . . or, well, something like that -  lol 

For clairity, just having a bit of fun - hope you both get what you wish for !
