Is it ok for a male friend to behave this way?

Aislinling
I have a friend who has a girlfriend, he suddenly started texting me every minute everyday, telling me about every small detail going through his day and he asks me what I'm doing.
He waits for me to sleep first even if I stay too late.
Telling me he hopes he's important in my life and he finds me interesting in a way that's scaring him.
He would casually joke about how he loves me and that he'd give me his heart.

I find it suspicious ngl but also I'm afraid I'm reading too much into it bcz he told me he loves his girlfriend.

please tell me what do you think about his behavior.

PS: I consider him as only a casual friend, I am not interested in him as more than a friend.
