Is there interest of here, or mainly just friendship?

There's this girl I like, we've known each other for like a while now. I'm older she's younger. We seem to talk a lot be it Facebook , texting or WhatsApping. She added me with a mutual friends of hers.

We seem to connect well, she usually ends up spamming me a lot with messages, like she won't just send one message it will be about 15 little sentences on a topic we're talking about. She seems to open up to me about her anxiety, her mental health, her childhood etc. She's quite shy. She seems to send me selfies of her a lot, I've asked her if she sends it to other guys she's like nah. She's not really about the attention. I've noticed she seems to tease me a fair bit, like pick up on typos , calling me old, and I tease her back. She sent me a couple of selfies of her in crop tops asking me which one she should post for her insta, again I feel she is teasing here? Whenever shes' out she'll always say "oh you should come to this place or you should go here" and they'd be around the area where she lives. She knows I'm interested in her. She also seems to ask me for advice on things in her life. She said that trusts me and feels comfortable around me.

We have met twice, once the first time she was shocked that she was able to have a conversation with me, normally she's her awkward self and can't get passed the hi stage, I did observe that she was always keeping eye contact with me and she was twirling her. The second time, she seemed to be a bit nervous, we had some selfies taken and I showed my best girl who pointed out that to me. She's send me like snapchat filter selfies with her singing with some of the cute filters. Also photos of her cats doing something funny or cute etc.
