Hmmm, just be really nice to her show her shes special to you and keep trying then when the time feels right tell her, and if shes not interested you can either keep trying or move on1. well...i don't know is it close or not but i been text-ing her quite daily
2. i don't think she know, but sometime in texts i give her a little hint...
3. i heard from my close friend, she does like another person...but they haven started yet(plus the guy also like her)
