We were both really sad to be leaving and she refused to let go when hugging goodbye. We'd had a pretty deep chat that morning though, so it's possible the hug was in response to that. I gave her a tiny coin as a kind of joke when I left but she said she'll "keep it for the rest of her life", totally seriously.
We've been chatting all day every day since I came home, she'll reply immediately, puts effort into the conversation and has been sending photos of what she's up to. She still hasn't mentioned her boyfriend, but now I'm just a bit confused - does it seem like she could be interested in me? She said she'd like to hang out when I suggested it (although haven't yet set a date / time) but now I'm not sure how to handle things.
