My friend just watched me get rejected by a woman in front of him and he said that he felt embarrassed for me

I walked up to this girl, and she just ignored me. My friend walked up to me and he was like "I felt embarrassed for you". I'm like "why" and he's like "did you not realize she was ignoring you? You literally kept talking to her while she was pretending you weren't there". I was too dumb to get the hint. He said that I'm not ready for dating yet.
