In terms of her feeling differently -- when you first met she didn't instantly want to marry you, then you got married and she didn't want to leave you, then at some point she did want to leave you. She was stubborn the whole time, made three decisions there and changed her feelings about the first two. That should prove to you that her feelings do change, and despite how she feels now, or what she says now, she may feel and do completely different things in the future. You have hard evidence of that.
