Love has never been about yourself. Love is about giving, not receiving. It's about how you can make your loved one feel happy & joyful.
When the definition of the word love changes, or your perspective of a relationship changes to, only you being the centre of it, in other words, centered around you only, and technically speaking self centered, i.e. to say being selfish; your relationship is bound to die(one day or another).
"A great relationship is about two things, appreciating the similarities and respecting the differences."
It never starts & ends on you. The more you truly love them, more you will be only see their good things and ignore their bad things.
If there is no love to bind the relationship, it's only the corresponding gains of both that can..
