Why are relationships so different from one another? Some can be as big and complex as the ‎relationships between nations and some can be as micro as the relationship between a mother and ‎her infant. The relation between a wife and husband or that between a boyfriend and his girlfriend ‎are well known to all of us and the commitments each partner has to offer with full sincerity and ‎sacrifice that the society we live in has agreed as a rule can be termed as codes of a relationship. ‎The code(s) that governs a particular relationship differs greatly. The only similarity that each code ‎has is an underlying thread based on love. The unit of each relation is an individual. So, if the ‎individual has a strong constitution, is mentally fit, understands that humans' nature is to make ‎mistakes, and is ready to forgive and forget; then there will no ‘toxic' relationships. ‎
