Early on in relationships, both parties tend to share particular hobbies and interests with each other. That is how we build chemistry. It is a system that has (for the most part) worked for a while now. Successful relationships tend to include a nice blend of similarities and differences.
Eventually, however, cohesion becomes the name of the game, and many couples feel as though several important aspects of their lives should become intertwined. This could include the purchase of a living space, either by renting or owning said property. It could mean establishing a shared inner circle of friends.
