Ok. I joined this message board just to put in my two cents on this question.
I don't know if this is too far back for anyone to read, but what the hell.
In the 1st movie Jean is definately wearing an engagement ring. It's a diamond on her left ring finger so...
But in movie two I was obsessed with seeing that ring again. Only in the very few shots of her left hand (ungloved)- it was easy to see she was ringless.
As for the convo between her and Logan... I've seen that movie 8 times and I still can't figure out if she says "I married the good guy" or "they marry the good guy"
"Girls flirt with the dangerous guy, Logan. They don't take him home *insert famke mumble here* "
So who knows!
