What does it mean when an ex who has moved on decides to offer to take you out and wants to buy you expensive treatments?

My ex visited our old hometown last Sunday and wanted to carry me out to a popular water spot with him. I went but I insisted he tells me if he has moved on. Later in the night he came back to my home and was open about his situation, saying that months after our breakup he decided to date but days after the first date, the girl came over to study at his place Nd they ended up having sex. He mentioned he didn't expect things to move so fast after they've just been together for a month even though he told her to slow it down. I thanked him for being honest and
that was it. The day after he got back home he called to ask if I want him to treat me to a skin treatment to do a procedure I always wanted when we were together. He even discussed it at lengths with me, even suggested I see a dermatologist first before having the procedure competed. What is this about?
