Hi and welcome. First off, I'm sorry you are in so much pain, of course this is devastating for you.
She was, obviously now, not being totally straightforward with you or she was confused (still means she was not being straightforward).
This is a time of transition for her and who is to say if this is a sound decision on her part, only time will tell. Has her family shared any insight with you?
You have a couple of choices. You could go to Florida to speak to her (with her permission), unless she has requested you not contact her. Otherwise you will have to just let it all go and see how things work out.
If in fact she decides that guy isn't for her, would you ever trust her again?
Just some things to consider. The most important thing right now is taking care of yourself. Is therapy an option? Talking to people, here, therapy, friends and family is important. Getting good counsel and people who listen and understand.
Try to sleep when you can, eat well (even if you don't feel like it), get out of the house, even if it's something as simple as going to pick up dinner, try not to isolate.
Basically it's looking after yourself and distracting yourself, while you have time to process your feelings.
