Well, there are some... I am not one of those. "Unconditional" is a strong word btw.
We are human and we have flaws, so I won't become blind to those flaws and act like a teenager in a platonic relationship. I just want someone who I can trust and count with when I need her. Love and be loved in return.
I am tired to watch friends in a relationship where the couple act like blind idiots to the point where they are harming themselves and nobody can say a word because "they love each other and that is all that matters".
