Relationships come in all shapes, sizes, colors, and meanings. You may most often think of romantic or marital when someone mentions relationships. But there is a whole gamut along the relationship spectrum from casual to committed with emotional involvement from minimal to intense. Everyone approaches relationships differently which makes one wonder how people ever get together to form even a casual friendship or acquaintance.
A relationship is an emotional exchange between two people over time and may or may not involve sex. All relationships have a level of intimacy, an agreed-upon set of behaviors and parameters and the responses for compliance or violation.
