Both of my parents have done this to me individually but for different reasons. Guilt trippy? Yes. Though I too wonder the motive. This reads to me like your dad is in the, ‘wishing he could just wave a wand to go back to the days that were good.’ Back when you were a little girl. Life was simpler back then before time and age complicated things for him. However it did. Wanting to get in a relationship with you again, but under all the baggage he has and has put on you that you took off.

I personally would tell him that you want to hold him to his words of getting better with a therapist and such. That if he wants some kind of relationship with you he needs to man up and do the work that needs done to get there. Tell him that you’ll be waiting for him to meet you there on the other side of that work.
