I'm a 30-year-old guy. My friends set me up on 5 blind dates in 6 months. Every single one ended with "Thanks, let's talk again" — then radio silence.

#1 — Conversation flowed, she said she had fun, I dropped her home. Messaged the next day. Read, no reply.
#2 — Conversation got quieter and quieter from the first half hour in. She said she was tired, went home early.
#3 — She was on her phone the entire meal.
#4 — We had a decent conversation, I drove her home. Two weeks later I drove past her place — saw her with another guy.
#5 — Yesterday. She told me straight up: "You're a nice guy, but I don't feel it."

I'm starting to doubt myself. I'm not handsome but I'm not ugly. Stable job. I can hold a conversation. What am I missing?

Honestly, I'm starting to dread the next one.
