Just because I feel a certain way about a person does not mean they will feel that way towards me. The word relationship comes from the base word relate. Two people must be able to relate to each other, in a possitive manner, in order for there to be a constructive relationship. Even then there is no guarantee that love will coexist between the two. We must be willing to admit this fact. Love does not alway work the way that we want it to.
This is why it is said love is unconditional. It is not reciprocated back to us due to our actions. It is given back out of free will. Honestly, I would have it no other way 🙂
