Above is stupid advice.
If it's Florence Nightingale Syndrome(Which I believe it is) just get sick again and have her look after you. By sick I mean a serious case of the man flu.
It's not a fix because if it is FNS there is no real love between you, just infatuation for all the wrong reasons. You yourself said you fell in love with her as she was basically caring for you and she most likely got a high being able to care for you.
If you want to fix it take your time, don't be visibly upset by it but give her a token to signify you aren't exactly thrilled about it("Of course i'm not happy to hear it but I understand.") then leave it at that and don't make a big deal about it. Otherwise just improve yourself, don't smother her with attention and work on improving yourself sexually(Get googling interesting and exciting stuff -- you can never know enough about sex!!). Do this and if she really does like you her interest will be peeked and she'll be drawn more towards you. And by "improving yourself" I don't mean improving yourself for her, I mean improving yourself because it's healthy and makes you feel good and independent(Go to the gym, work out, socialise with friends, be happy in general and don't let things get you down).
No offense games but your advice is stupid. The mans ex fiancé is now saying she doesn't want to marry him and that she wants to keep her options open and you are telling him to pretend he is sick and google about sex.
OP...I likely you have been reading these signs for a while now. It's over and only drastic action has a possibility to get her back. Tell her you want a break to think things over and kick her out for at least two weeks don't respond to her or be affectionate in any way. If she begs to get you back then you can re evaluate...otherwise, once a woman has lost attraction, you have to cut the cord. Anything else results in an even further loss of attraction.
