Hi Peacetoday, I think if there is some contact between your D and her dad, that's for the best. As long as the contact is healthy and positive, I would encourage it.
As for OW part in the contact. Again, I think as long as it is healthy and positive that's okay. Perhaps she is trying to help open the door to more contact - IDK. But best to take a neutral perspective on her motivations unless something else becomes apparent.
I know a guy who stopped being in touch with his Dad, due to his Dad's problems with alcohol use. It's a burden to carry for sure, and if the non-contact can be broken - even if the R doesn't become close again - it's better than your D carrying that burden I think.
I do hope that this proves to be a positive step for her xx
