What you miss is already inside of you but trying to connect you need a peripheral. 
Suppose, you miss your nativity coz you have lived there, that’s where your grandparents lived and you also lived with them with your parents. Now, due to social pressure you’re living some few hundred miles away. If you watch closely you can chew by bringing your memory but to really feel the texture, you have to be there in person. The experience is always there in memory but to enjoy you need to go to your nativity. Your village becomes a peripheral when you are living somewhere.

In Love, You have an inner male consisting of your father, brother, relatives, boss, colleague, hero..etc. Your inner man consists of all the man met in your life. The inner man is called animus. He is the perfect man for you, he is your man but how to connect your inner man? Simple you need to find an outer man who resembles little of your inner man. Yess! here, where your boyfriend comes and troubles you. When he is in love with you that’s the time you are able to connect and have a close relationship with your inner man. Your lover acts just as a peripheral to connect your inner man that’s why when he ditches you, it is impossible for you to connect with your inner man hence you cry.
Actually you cry for not being able to connect your inner man because of the absence of outer. Hence your lover acts as a connector to your inner man and nothing else.

Same here in taste. Long back you would have dine in some restaurant in some city but you crave for it now. If you listen, the taste inside of you and you can feel but cannot enjoy. To enjoy you need your favourite dish to present in the peripheral, without it is impossible to enjoy.

This is the reality, 
If you know the truth behind what is missing, you can come out of it.
