It's funny, I actually posted something about this subject a while back on another forum that would likely be relevant here. A lot of confusion stems from the fact that we use one word (love) to describe several different types of brain activity. On the other hand, the Greeks had four different words to describe love, each with their own separate meanings.
First, we have
storgē. This kind of love is basically affection. The kind that naturally occurs for most parents towards offspring. So, it's the familial love you mentioned.
Next, we have
philía, and this is a kind of "brotherly" love. Loyalty can fall under this definition as well (nakama, if you will). So, this could be considered platonic love, although it can also be familial as well, depending on how close you are to your family.
Third is
érōs, which is desire. This kind of love can sometimes be a mixture of timing, attraction, and circumstance, as there's rarely any logic to it (e.g. love at first sight). While this type of love is usually thought of as the kind someone feels when they're attracted to another person, it can also be applied to thing like food (ex: I love pizza). This seems to be where most of your questions lie, so I'll elaborate a little. In the hypothetical scenarios you mentioned, you have a
desire for this person, but then you find out they weren't at all what they seemed to be (or what you hoped them to be), and thus you
lose your desire for them. You may still care about the person in a platonic manner, but you lose your
desire for them. There's more to this, but I'll get to it in a minute.
So far, all of these describe feelings people have towards others. However, the fourth one is not necessarily a feeling, but rather, a choice. It's known as
agápē, which is the purest form of unconditional love. This love is selfless; it gives and expects nothing in return. It's the kind of love that would compel someone to give up his or her life for someone he/she cares about if he/she deemed it necessary. It's unique, because with the other types of love, you either feel it or you don't. However,
agápē has to be a conscious decision as most humans are incapable of actually feeling this way towards someone else. Granted, feeling the other three love types will make this easier, but it's really difficult when someone has done something that causes you to no longer feel one or more of the other three.
So, to answer your question, romantic love (when you're in a committed relationship, anyway) is at its most basic, a combination of affection, camaraderie, and desire. Ideally though, it should include
agápē as well, because there may be times when you feel no desire for your significant other, and if you don't make the conscious effort to continue loving that person, your camaraderie and affection could crumble as well.
Hope that helps.
