What does it means when someone has strong feelings for someone what makes people attracted to them even if they are taken by someone else?

When someone has strong feelings for another person, it often means they experience a deep emotional connection, infatuation, or romantic interest. Attraction can stem from various factors, including physical appearance, shared interests, charisma, or emotional compatibility. People may be drawn to others, even if they are in a relationship, due to the thrill of the forbidden, unmet emotional needs, or the allure of novelty. Ultimately, strong feelings can complicate personal boundaries and lead to intense but often challenging situations.
