I got so confused by it... If you understood it, even a little bit, what theories do you have?

In my perspective, it isn't a book about love or terror. It's a study about we can recognize. Let's put it this way: all our world is constructed through our ability of association (not all chairs are the same, but all of them are chairs, because we can see some aspects in common between them); this example tell us that they are replicas but that they are not equal, so, all replicas are almost the same, but not totally. The same thing happens in the novel: Harey might exist, we can't be assertive in this matter, although it also doesn't matter. What is important about this replica of Harey is that she is recognizable by Kelvin, which does not really matter if she looks excatly as the real one, but that our narrator sees her as a replica, as something that looks alike. Their relationship is the same that was on earth, but was also different. The way he gets exausted at first, remiding us of the end of their relation on earth; then, the way they start to get along, and to truly love eachother; and, to end it all, her suicide, the suicide of the replica is just as alike the suicide of the real Harey on earth, being the only differentiator in the two cases the reason on the killing of the own. One is because of Kelvin abandoning Harey, the other it has the cause in Kelvin not being able of letting Harey go.
They look the same, having only a little difference.
So, my english ain't the best, but I hope it gave a little explanation in this amazing novel.

I think a major theme of Solaris is the impossibility of understanding.

Science-fiction is usually optimistic about space exploration, but Lem's novel has something quite different to say: We can’t possibly understand an alien consciousness. We can’t understand each other. We can’t even understand ourselves.

It sounds bleak, but I think it's realistic. We tend to assume others are like ourselves, and in some important ways, they're really not.
