Weird feelings...

I've been talking to this guy for a week, and he's started pursuing me. For some reason, I feel rushed, but I also don't want to make it seem like I'm not interested in him. What should I do? I'm not new to love at all, but I guess there's just this odd feeling in my chest sometimes. I like him as well, but not as much as he likes me, since he told me he'd been admiring me for three weeks straight, and I'm only just developing more and more feelings for him (as I was writing this we talked it out, thank god he can actually tells me things like this lowkey happy that he can tell me and we could resolve it).
