I’m not sure if she’s into me or not based on her Snapchat responses?

Me and this girl (who’s pretty shy) had been exchanging glances for a few weeks. I tried talking in person to her but she seemed nervous. School break came around so I decided to message her on Snapchat.

She initially seemed really interested with fast responses and enthusiastic replies. She started to get really slow at replying but kept up the positive responses.

It eventually got to a point where we’d only reply every few days until recently. I sent her a selfie of me in a jacuzzi and she obviously seemed attracted based on the selfies she sent back.

She’s gotten a little faster at responding (a few snaps a day) and seems comfortable based on the selfies but she still takes a few hours to respond.

I feel there’s an attraction but I don’t know if she’s actually interested, particularly as she only seems to reply faster later at night now, rarely texting during the day.

I don’t really know her well enough to tell her my feelings. Additionally, where I’m from, relationships usually start more from a talking point online rather than asking on dates. This is why I’m analyzing her Snapchat responses.

Can anyone give me any insight into this situation?
