Confuzcious, at this point you're probably finding out that unconditional love is a rare thing. Even if the witnesses and others preach it, it's pretty hard to find it in the world. Of course, in our everyday dealing with people, nobody will feel they owe it to you, not to mention the fact that it can't really happen through a personal psychology that thinks in terms of who owes who what anyways.
Loving God does not mean people should be doing things a certain way or that things should be such and such a way. There are very few people out there who will just unconditionally accept you as you are all the time anyways, just as you want others to be a certain way yourself. Most people just can't accept life as it is, but invest so much emotional energy in resisting it or in just contemplating how unsatisfactory it is.
Love just means accepting everything and everyone, it's not a feel good thing to bolster people's egos as most people seem to think it is. Remember the bible says "if you love those loving you, what reward do you have?" Now from the individual perspective someone may very well be like "well I'm not expecting this guy to love me back anyways so screw him!!" But if you actually are loving rather than thinking of love as some commodity that gets exchanged between people, then it's real, and not just from a thought - even if that thought is "I love God and neighbor."
A broken heart is a great opportunity to open to this, but make no mistake - it isn't about feeling good. It's not about feeling bad either, but just accepting the truth. Truth and love go together, one without the other will just leave you empty.
