If your dad is still under the impression, 10, 15 years later, that you chose to cut contact, well then it stands to reason he wont make an effort as that would just mean he's being pushy.


Don't leave it up to him to clear the air, that's obviously never going to happen.


Go visit, and when you two are alone on the farm, ask him to clarify why you guys went no contact for so many years.


Then you evaluate the relationship from there.


Because while your story still has so many holes, its hard to make a wise choice regarding something that possibly affects the rest of your life and other people too.
