Search Results: are my signs obvious

We started texting each other around 3 weeks ago, we've had 4 conversations since then. Every conversation has flowed, he's been asking questions back, the good signs. We both have solid, obvious interest in each other.
The 1 big problem is I've texted first the 3/4 conversations we've had, the only reason he texted first was to apologize for falling asleep. We aren't dating, but if quarantine didn't exist we would.
I've sent him a text in the last conversation we had 2 hours after he texted, then 1 the next day, then 1 a couple a days later (3 days ago), we are using snap chat and he's been on it (his snap score increased by a couple of points.)
He's done this before after the 2nd conversation we had, I texted him like 3 times then he answered what I sent him. He doesn't seem to mind not chatting for a week but I don't know if that's normal.
by the way we're both in high school, and are both 16 years old. I'm a female, he's a male. I've never texted a guy before and honestly I don't think the guy texted other females that much before. He's been a couple of relationships before, I've had none.

And is it obvious when a guy catches feelings?
Will he start acting weird or even distancing himself from you?

~~How do you act around someone you've developed feelings for / started developing feelings for? 🤔

I've currently got a guy acting quite strange around me (see my other recent questions).
