I find almost every girl attractive but idk what love feels like. Help?

M20s here.

So basically I find almost any girl sympathetic/cute. Like, I can vibe with them, looks are fine, etc. But I literally never feel "love".

Idk what that even means. No butterflies, no "can't live without u" stuff. Just flat attraction to almost everyone.

It feels like I’m faking it whenever I date cause I just don't get that deep feeling others talk about.

Just wanna know:

1. How do u actually tell the difference between "she's cute/nice" and "I love her"?

2. Is it a slow burn or am I supposed to feel it instantly?

3. Anyone else have this broad attraction but zero depth?

Not depressed or anything, just genuinely confused how this works. Thx.
