wow i well i lived 3 years without my parents knowing about my bf cause they would kill me said i was too young and stupid but hey im still with my bf and my parents are getting used to eat if you pass the 3 year mark you will be fine its going to be hard and frustrating but if loves you it will be something you two can work through now about your mom she is passing the line but hey your her daughter all i can say is good luck and if this doesnt brake you it will only make you and your relationship stronger
