When they discover they've got a crush:
She gets crushes rather easily, finding herself infatuated with all types of people, but you'd have to be truly special and interesting for it to last. She has a tendency to fall in love with the idea of a person rather than the actual person, so when she's truly interested in someone, she tries to be more realistic about the situation and get to know who they actually are.
How they confess/hint:
She might not have much confidence in her writing, but it sure as hell would beat her spoken confession. She spends countless days and nights thinking over the perfect words to write down, the ones to win your heart and properly get her feelings across to you, and it would probably take a few months before she finally gives you the final draft. Even then, it could easily be blown off as just a piece of literature and not an actual confession letter, something she'll happily fall back on should you not feel the same.
How to win their heart:
Let her in, and be open with her. She's a woman who loves the little details, and she promises not to use them against you; she just wants a better view of who you are as a person, both good and bad. She likes someone who's confident in who they are, and knows who they are as a person, but who isn't ashamed to show their weakness to her.
How to break their heart:
Shatter her illusion of who you are as a person completely and utterly. It's a bit easy to break her heart because of her head in the clouds status when it comes to love, but she's not an idiot. She can tell when you're lying to her, trying to make yourself look better, or when you're just trying to play her for a fool. She'll be long gone before you even have a chance to realize she could tell you were playing games with her.
Things that make their heart flutter:
She loves dancing to a nice, slow song, being close with her lover, especially under the light of the moon. She likes holding hands, and really likes when you pull her hand up and give her knuckles soft kisses. Hearing you give her writing genuine, non-generic compliments also makes her heart flutter.
Their type:
She really does enjoy the rough and tough type, perhaps appearing a little frosty on the outside but being truly charming and kind on the inside. She likes someone who knows what they'd like out of life, who attempts to follow their goals and tries to stick to their ideals.
Goals in a relationship:
She really would like to be married, though she had doubts it would happen before you. She wants a nice, small wedding, having thought about it for awhile after you'd proposed to her. She's not so sure about kids, but she enjoyed being around Jack, so she can't say she's entirely opposed to the idea.
