These effects don’t just stay internal—they often spill into everyday life. If one person is more emotionally invested than the other, it can create tension, disappointment, and even heartbreak. In more complicated situations, like overlapping relationships, it can damage trust, lead to gossip, and strain friendships.
There are also real physical risks to consider. Unprotected sex increases the chances of sexually transmitted infections and unplanned pregnancies. Even when precautions are taken, the stress of “what if” situations can weigh heavily—especially if there’s little support or communication.
