Love disappoints me.

Now that I finally found someone who loves me, you know, this awesome guy, I think I'd be better off alone. I'm really confused. I liked him, a lot, just before I found out he liked me back. The first date was amazing, and now, I barely feel a thing when he kisses me, when he hugs me. We haven't even made a week yet! What the actual fuck is this shit? Why do I feel this way? Isn't this supposed to be spectacular, magical? I don't even get butterflies anymore when he tells me something sweet. I saw him today, and I went back home earlier than I had to because I felt so wrong. The thing is that I liked him just a few days ago. What's happened? Love is just an invent of industry to sell teddy bears, chocolate and fucking flowers (in my case, CDs). I feel so wrong, I don't wanna hurt this boy, he's really amazing, in all senses, but I just... I just... I can't even phrase it.
I had the illusion to find someone someday who would make me forget everything with just a caress, with a word. Someone who would love me, and who I would love back. I thought I loved him. I'll hate myself if I ever hurt him. I swear I will.
Is this it? Is this "love"? Because if this is it I would definitely be better off alone.
