<human>: Could you distill the essence of the text into 1-3 sentences?

As I said, the girl I've been with for three years (she has only been my fiancee for half a year, if that needs clarification) is still attached to her ex boyfriend. She's not cheating on me, or even really talking to him or anything, but she constantly talks about her relationship with him, and tonight, after we both ran into him, she gets emotional (not to the point of crying or anything) in the car and makes a FB status about how "you really messed me up". I'm pretty positive it was directed towards him, even though no one was tagged.

I feel like I can't stay in this relationship constantly thinking I'm just her silver medal or something. Am I overreacting? Is this normal for women?
<bot>: My fiancee is not over her ex. Should I cut my losses and find someone who won't see me as 2nd best?
