Is she into me?

Anonymous
Hi,

I'm not sure if she's bored / into me, please help me out here.

Timeline:
I started texting her a week ago on Friday, then stopped on Sunday night.
Next week Saturday I texted her again. On Sunday evening I thought the chat came to an end again, but after the topic closed, 2 hours later she initiated and started a new topic and we're still talking.
We had a late night text conversation from 1:00-2:00 AM on Sunday.
It's the following Monday today.

She does put effort into her chats and I'm not the only one asking questions and bringing up new topics.

Pros:
- We share the same humor and find each other amusing
- Late night chats (had 2 in total as for now)
- She doesn't end the topic, she leaves open ended comments, etc.
- When we chat at night we text continuously, we don't leave the chat.

Cons:
- She takes her time to reply (typically 5-40 min.) I don't know if she's playing hard to get.

TL;DR
If she shows signs of interest but takes her time to respond even when online, is she into me? (she doesn't end the conversation either.)

Shy? Playing hard to get? Friend zone?
Yes
No
