In a relationship if you do not get back that what you expected, does your love change?

People say love is a two-way street, and love conquers all, in reality is that true for most? Think about the relationship you are in, or have been, you went into it with an expectation of something (you know what the “something” is/was). If that something never materialized or manifested itself in the relationship, did your love change for the other person? If it did, how can you say love conquered all, because it didn’t? The true is though love can be emotional and it can be felt, it is not an emotion or a feeling. Love if not a process, is an attribute you have. If you love something, you love it, to stop loving it is not so much what it or someone did, than you coming to that conclusion independent of their actions. However, has your love changed for someone depending on their actions, and if their actions made your love for them change, how can you say there was any true love there to begin with?
