Yes. All relationships are inherently selfish. People are with others because they need something, want something, want to avoid something...etc.
The selfishness of love and the recklessness it brings about in us is perfectly captured in this short poem from Yeats:
The Mermaid
A mermaid found a swimming lad,
Picked him for her own,
Pressed her body to his body,
Laughed; and plunging down
Forgot in cruel happiness
That even lovers drown
This must be sad to go through life with this outlook. However, it is true in another perspective:
I did need something. I needed him by my side ever since I first set eyes on him all those years ago.
I did want something. I wanted to build a life with this guy and share every aspect of it with him. When we were teenagers we had no idea what the hell we were doing, but it worked out.
I did want to avoid something. I wanted to avoid the prospect of waking up in the morning and rolling over and not having him lying next to me. He was there, at least for 33yrs. of my life.
We were reckless. We graduated from university together and bought our house together when we were 23yrs. old. We lived here for close to 30 yrs. building our life together.
I'm a selfish bastard!


excuse the "divorce" comment.
