The truth is that she has found a place where she can be herself truly, where being a warrior and a woman aren't mutually exclusive, because do you think she could be both where she came from?
Veur treats her with respect and admires her as a warrior, and obviously finds her attractive as a woman, look at what she herself says her future would if she were to return, she would a second wife, never allowed to pick up her sword again, relegated to a life she doesn't want, hidden from the world in some palace, likely forgotten and shunned, while in the West lands she is respected, admired, seen as an equal by everyone else, she can live her life as she desires, she is not forced to choose either being a warrior or a woman, when offered a better life I think most would choose it
