Seeking expert testimony is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I believe that I can help.
He could not have felt that you were not into him. You pursued him and made your intentions very clear.
He lost interest in you, or more likely found someone else.
You asked a friend who probably did not want to get in the middle of your personal problems and so feigned ignorance if he knew something.
You have learned something valuable about this man.
He lacks character and moral strength and acted in a very cowardly manner. He cut you out of your life like you were a skin growth and not as if you were a real person with feelings.
You need to do your best to get over him. When you do you will be very thankful that this relationship ended, although he did not give you the courtesy of getting closure.
Let me recommend a book for you:
I wish you great success in finding closure on this failed relationship. Your life will change and you will find happiness again in a relationship, but this time with more satisfaction.
To that end I shall you you in my prayers.
