How to text my crush Watch
If she initiates a conversation, then I am generally fine but I struggle to initiate conversations with her. Whenever I try, I think she feels sympathy for me. On the last non-exam day of school, I had my yearbook, and I pushed myself and asked her to sign it. I think she was really happy that I mustered some courage, and she signed it with "lots of love <name> x <3" and you can imagine how embarassingly happy I was about that. The other reason I think she perhaps likes me back is because she is somewhat touchy-feely with me. She fist-bumps me quite often, holds on to my arm if she needs help with some work, brushes against me when we walk and in sciences if we are doing a practical and i'm washing a beaker or something, she coincidentally does the same and stands really close to me. Finally, if she catches me glancing at her, she smile; waves; and says hi. I've caught her looking at me a few times, though perhaps I am overestimating that. The last thing I would say, and I hope I do not sound like a giant douche, is that I am known by the girls in my year for smelling good, as I have impeccable hygiene (borderline germaphobia - yet i still have mild/low acne) and I use and know my way around quality colognes. All of her friends compliment me about how good I smell, except for her, which is rather frustrating.
I'm far more comfortable with communicating via social media, i.e. snapchat/instagram etc, though I do not have her number. However, via social media, she's only really messaged me for homework help.
Apologies that the question has been structured poorly, I needed to hurry and type this up as I still have more biology revision to do.
Tl,Dr; How can I start a real conversation with her via text/social media? Should I ask for her number? What should I say?
