何时该界绍朋友给家人，＇姐姐的故事＇的联想

JJ was not happy about her bf didn't introduce her to his family during family gathering. I guess I have the same problem as her bf. I usually don't want my family to meet so many people unless I am quite sure with that person. So I travel and do many things without gettting that person's involvement. My concern is to protect my family and also feel not ready to the relationship. Now reading so many comments, I wonder..... and would like to hear JM's says.
