Females dont has a rule hide their feelings we are often referred to as being over emotional, we only hide them when unsure of a possible relationship or if we have been badly hurt.
If this woman is to marry you because of your culture then she has yet to love you, she is being the good daughter and following her parents wishes, however if it isnt cultural there is a serious issue here,one that needs to be rooted out before marriage is considered any further
A mistake is always forgivable, rarely excusable and always unacceptable.
