Hi Jennifer,
This sounds counter-intuitive but what I would do:
1. The next time you see him, just sit quietly in the same room as him. Watch a movie, read a book. If he asks about you just say a peaceful, “Good.” If he says anything controversial or contrary, just say, “Interesting. I haven’t thought of it like that.” This is to give both of you the experience of being peaceful around each other.
2. Ask him to help you, give advice or get his opinion on something. Again, no matter what he says, keep you mouth shut, and just say, “Thank you.” This gives him the experience of acting in the role of Father.
It WILL get easier. When you are more than half his age (i.e. he had you at 30 and you are now 31) expect a definite energetic Shift. Look forward to it.
Best,
Inky
