Sadhguru
Why do my relationships keep ending in complaints and bitterness, and what can I do?
Manage yourself, not the relationship
The many small frictions of a shared life can't be managed on a daily basis, so manage yourself into a joyful being. Then your relationships won't be need-based.
So the best thing is to manage yourself so that you are a natural, exuberant, joyful being. Then relationships will happen, and they will not be need-based.
