plb@m, I agree with Jodi. You did what you felt was best, and from the sounds of your dad, I would have done the very same thing.
And as Jodi said, "... you feel what you feel...", and I think that says something about
you. You genuinely care about other people, which is possibly (probably!) more than can be said about your dad. You're a good mom, and you love and care for others. You can't change who you are, and you shouldn't. But you can't change your dad, and that's not your responsibility.
I can just hear my psychiatrist saying, "He's not talking to you? GREAT!!! Less stress in your life."
You make the choices that are right for YOU and your family. Don't compromise who you are, hon.
