I sent the letter off to my father... Do you think he'll be happy or upset?.

I sent a letter to my father letting him know I'm his daughter. My mom got pregnant by him when he was having an affair with her and cheating on his abusive wife. My mom never told him I exist.... Big reason is because he got a life sentence for killing his wife after she murdered all 3 of his kids in cold blood. Which no one was surprised about because of how abusive she was to all of them. She was the definition of an evil step mother. I wrote him a letter telling him who I am and wanting to talk on the phone or come to meet him. If you were him how would you feel about it?
