Sex Worker Ghosts on Client — Should He Try to Contact Her?

Savage Love Letter of the Dayby Dan Savage
I saw a professional for 2+ years on almost a monthly basis. I saw her at her home and she was comfortable enough with me that I had even met her sisters. The last time I saw her we parted ways well as always. Then nothing. I attempted to contact her and her phone didn't work. The last time I saw her, her phone was on the fritz. I am hoping, probably naively, that her phone died and she couldn't recover my info to contact me. Is it wrong to send flowers
