Should I or wait

Ok so yesterday while at work, my bestie coworker came to me and told me that our patients dad has been staring …..at me, I didn’t believe it so I’m like um no he not .So as they were leaving the appointment, I said bye thanks for coming have a good weekend” and the dad started to smile hesitated to walk out the door and said to me. “I’m so sorry but you are very beautiful 🤩. I started to blushed and looked back at my bestie. He asked me was I married. And proceeded to give me his number( we exchanged) . I go back to my bestie and said WTFFFF (that has never happened to me before) . Should I wait for him to reach out to me or should I reach out first? 😬
