There's nothing like being in love!!!
There are many ways to say "I have a romantic interest in that girl [or boy]." I can think of a few:

1. I have the hots for that girl!
2. He was making goo-goo eyes at her.
3. I am eat up with her!
4. He is head-over-heels for her.
5. She is carrying a torch for that boy.
6. Oh, yeah! She's my main squeeze!
7. She is crazy about that boy!
8. He's fallen for her.
9. He is serious about her.
10. She has a "thing" for him.
