The Optimistic lover blindly skips into a relationships and “lets the cards fall where they may”. It is all good, after all. Often expecting to “get lucky”, even if only by holding hands.
The Pessimistic lover uses a “worst case scenario” thought process in order to emotionally prepare for the devastation that will inevitably ensue once within a relationship.
The Realistic lover looks at any relationship as a learning experience, regarding it as neither good nor bad. With no expectations, the realist is ready for anything.
