I have to say I am amazed at those who think she can just turn off her emotions in a 24 hour period. Two days ago, she had no reason (that she knew of) not to love this guy; yesterday she did. You really think she can snap her fingers and all the feelings will just go away? Give her a break, please. She's dealing with an almost surreal set of circumstances here.
OP, luck and strength to you. Take care of yourself.
