How do I, a 36F and recovering people pleaser handle a situation where a good friend ghosted me for 9 MONTHS only to pop up back into my life like NOTHING happened

At the end of last year I moved out of state which is when the ghosting started. Initially I gave my friend the benefit of the doubt but after 6 months of trying I gathered whatever self worth I had left, mourned the friendship and moved on. Imagine my surprise when today my "friend" has been nonstop love bombing me with DMs, comments on my social media posts and texts like NOTHING happened. I can't imagine having this conversation face to face, much less having to do it via text since you know...I now live like 500 miles away but I can't pretend like nothing happened. What do I say?
