I’m thankful I didn’t have to deal with this situation. I have seen some discord when my friends have entered a second marriage where children are involved. They were not treated nicely by the stepchildren when their parent passed away even though they were taken care of. I honestly do not know what I would do so I would not criticize you or your actions. I do think it’s sad that your stepmom chooses to not forgive you. That must be difficult for your father who loves you both.
