is she into me?

Hi all,
So I was speaking to this girl late last year, met on a date once and talked for a good few months before she said she wasn't ready for a relationship which hurt a lot as i was head over heels for the girl which is rare for me ill be honest.
Fast forward 7 months and she came up on my linkedin (of all places i know) as a suggestion to which i screenshotted and sent to her as a laugh. We got talking but nothing like we were originally with replies being very slow mainly from her side but i can also take a bit of time as i don't want to look 'eager' as such. There's been no flirting or any mention of our past whatsover. The chat kinda drifted off last week to the point where she didn't reply for like 20 hours and then she actually opened and ignored my message on the thursday night. I then put a story on my private snapchat on the Saturday after to which she replied and we got chatting again. Again replies were really slow to the point where it felt obvious that she didn't want to talk to me so when she eventually replied i just opened and ignored the message. She then messaged me within 15 minutes of ignoring starting a completely different conversation and have been 'chatting' since. Replies are still mega slow but i'm confused to what she is actually doing? I don't want to get too invested and hurt again but if there is a chance i'll be honest i'd jump at it.
Obviously completely different to last time as replies would be pretty much instant and i could tell she was invested in me in a way. I know that i'm probably not the only lad on the scene at the moment but it is starting to confuse me as to why she is actually speaking to me.
