You are over thinking this ItHurts. Yes, she could be pondering all the things you mentioned...like missing you here while you are NC. But if she is afraid you have really moved on because she is considering FL, or even goes to FL, what option have you given her?
And why be subtle? Being subtle about asking her out means you are either unsure of what you are doing, or not confident in what you are doing. Just ask her out. Act as if you two are still in your honeymoon period from a few weeks ago. You have already said she is warm to you. Tell her you want to take her to her favorite restaurant or something before she leaves. Act as if she already is leaving and you are ok with it when you are around her. Show her you are fine with whatever she decides and you respect her RIGHT to make her own decisions. Do these things and be the H she would be a fool to leave, and she wont leave...unless she is a fool
