i was invited out by a girl on a saturday, went great , on her own without me asking she stated she is single and only relationship she had lasted 3 years with it to end because the guy became physco and thinking she was cheating went through her phone etc they left off on good terms tho she said there was one time he asked if they could be friends and she said can't just be friends with him, she asked me first if I was single and if I was talkin to other girls I said no, even asked me about my ex which I told her of, time for the bill comes and she the first to grab it wanting to pay. I payed saying one of the benefits of being a woman was for a gentlemen to pay for your meal, she made me pinky promise she will pay next time. night ended off said she had a great time we connection a chemistry relating to each other with literature and saying a lot of common interest at the same time in unison so basically we have a lot in common, made her laugh etc, she even complemented me on my intelligence saying she never thought she would meet a guy like me and I remind her of her best friend, text her that night thanking her had a great time hope to do it again, she responded 2 days later saying no problem she had a great time enjoyed my company and thanked me , I said your welcome hope to do it again and she replied immediately saying anytime posiedon, I asked how come she call me that and I didn't get a response. didn't hear anything from her for 5 days, I text her saying "hey little kardashian" (cuz we joked to each other and she even brought up how she looks like kourtney how she looks like a kardashian) she replied "hai :3" and I said "=-* wats up" and she didn't reply and now its been another 5 days. my questions are what does :3 mean? is she still interested? what should I do? I'm really confused advice would be much appreciated because she's amazing
