Well, precisely? Losing two of your closest friends.
Research reveals that, on average, having a new romantic partner pushes out two close friends from your inner circle. Falling in love comes at the expense of losing close friends, because romantic partners would absorb time that would otherwise be invested in platonic relationships, according to researchers.
The research showed that men and women were equally likely to lose their closest friends when they started a new relationship. Previous research has shown that people typically have five very close relationships – that is, people whom they would turn to if they were suffering an emotional or financial trouble.
