WHAT THE FLUFF DO I DO?!?!

So I confessed to my crush for a year or two, and guess what. I TOLD HIM IN JAPANESE!!!!!!!!!

So here's how it happened:
I thought to myself in the hall, "why not tell him? He is right there after all." He was a couple feet away. So I went up to him and asked, "do you want to know a phrase in Japanese?" Then he said, "sure." Then I said, "aishiteru." (Aishiteru means I love you in Japanese.) Then he asked, "what does that mean?" And since i didnt want to embarass myself and make it a sticky mess, (there were a TON of people in the hall.) i told him, "look it up." Then he said something when I was leaving, "I think it means.." Then that was IT. I NEED HELP. ASAP.
