Nope. If someone doesn’t reciprocate that’s an indication of their level of interest. This is true for friendships and romance. If the other party is always a passive recipient of attention, they aren’t interested in the relationship. It’s pointless to invest one’s time and emotions into such a relationship.
I agree. We could use a different terminology to make a much better sense out of it. Perhaps the word "give" and "take".
If I am the person giving and the other person is just the one that takes, without giving back anything, then nope, I am leaving that relationship for reasons that should be obvious. Another term to call the "takers" would be "leech" or "parasite". It does not sound good now, does it?
