"We are in relationship all the time, and our relationships are a reflection of our own inner world. ". To learn and to grow, you need relationships. " So aptly said.
Where we falter is when our ego starts telling us you are better than XYZ. You deserve to be treated better. We start viewing the relationship as a combat and start devising ways to prove we are better . We even manipulate just to show ourselves in "better than "ways.
The very relationships which were meant to give us joy , starts giving us stress and result in a never ending struggle.
