from my point of view , let your parents know about it
and dont think much about dating and all .. what is most important to you >? if you both really love each other then i think most important thing is to spend rest of the life with each other so if you have to suffer that dating part then i think its ok ..
parents will understand the feelings of you both and also ask your BF to tell his parents about it so that if both families want to meet each other then it would be fine i think
