Always be there to listen to her, look her in the eyes when you talk. Make small talk, and try and let her know she is an important person in your life. Admitting your feelings to her in public may embarrass her or put her on the spot, so if you decide you let her know how you feel try to work it into an intimate conversation.
Well, find a time a time to talk to her alone, through text if it's necessary. Do you know why she's trying to hide it? Is it out of simple embarrassment, or is there some specific reason behind it? Because if she's feeling too shy to confess it... Well, simply confess yourself. cx I know it's easier said than done, it was actually the same way with me and my girl friend, and she ended up confessing first. And... I happily and slightly embarrasedly told her the same. I don't mean to say that my experiences count for all, but take a chance! If you two know you love eachother, don't hold it back any longer. Love finds a way. uvu
