No problem. This is a big shift in logic conceptually. Everyone handles this differently and that is OK. We are all human, frail, emotional and occasionaly irrational.
I never knew my father, never saw a picture of him. It was somehow alright as I grew up, I didn't feel that I was missing anything. As I became older (much), I began to quizz my mother. She had some stories but candidly she knew very little. I ultimately discovered who he was using DNA and in doing so discovered a whole side of my family that I did not know. In the process I discovered some other "family secrets" and it made me realize how little we understand why people do things. Humans. I wanted to know more about me through learning more about my roots.
The match you mention is not going to change, you are right, he is your father. How you deal with this complicated issue is up to you. Your choice. There is no fault here and you have no obligation other than to yourself. Good luck, I am sure you will make the right choice.
