One of the worst temptations is to flirt when you are in a relationship. Flirting can be verbal or written communication as well as body language by one person to another. It may even be interpreted as interest in a deeper relationship with the other person. If flirting is not controlled it can even lead to you cheating on your partner. Flirting will also cause jealousy and insecurity in your relationship. Refuse to give into this dangerous temptation if you want to keep the relationship strong.
