You have to Open alot of Oysters
If you want to find that Pearl in a Oyster you have to open alot of Oysters. Well relationships can be the same way. People date and date for years before finding that right person. Pearls come in different colors. White and Black. You could open alot Oysters and find a few White Pearls but finding a Black Pearl isn't easy. When you find that Black Pearl you do anything to keep it. But sometimes it can slip out of your hand and get lost. Black Pearls can come in different shades of Black.
Relationships of any kind work the same way. You have to work at them to keep them. People call me asking if their BF/GF is the one but they find out that the answer isn't what they are looking for. The is why I like to be phased this way, "Are my BF/GF friends?" Shouldn't you be friends before a Higher Level of your Relationship.
It all helps if you phase your question carefully. Or just be careful of the answer.
