The unconditional love myth, as described by Donovan Sharpe

[ada]

...
And this "unconditional love" BS only gives unrealistic expectations.

It is unrealistic, but not as an expectation, just as a possibility. And if it wasn't unrealistic, or something of the norm, it wouldn't be able to evolve us.

Even though you feel that your love for your friend is conditioned, I imagine that it transcends everything physical, you could spend time apart in this reality, but perhaps in truth you already are close and never were apart but briefly.

I think that it's good that you rise up and take responsibility for yourself, whatever it brings you to.
