Being my mouthpiece, or advocate would have you testing limits, tiptoeing around self-erected anvils falling, overthinking moves and stuck in neutral.  Especially these days where whispering niceties, compliments and honesty gets SWAT called in.  Steps back slowly.  Bouquet of roses pulled back into my sleeve.  
Give them what would help you, assure them, reassure them, give them a straight eyed “Yes I like you.  Yes, i want to get comfortable expressing myself to you.  Yes, you are safe sharing your heart with me.”  Give (her) time.  Wait for feedback.
