I don't really want to call myself an incel but I'll answer from the standpoint of someone who's extremely bad with women.
When I was in my mid 20s, a friend gave me the phone number of a 35 year old woman he wanted to set me up with. I figured it was at least worth a shot. I texted her to ask her out (her preference, according to my friend she didn't like talking on the phone). She agreed to a date that Saturday. This was about Monday. On Wednesday, she texted me back and gave me the "actually I'm busy with work for the next jillion years". I said okay.
Asked the friend about it. According to him, this woman told him that she changed her mind because I hadn't texted to ask about how her day was going, in between the 5-ish day her out and the actual date.
To this day, I honestly don't know if I'm a massive autist who missed something stupidly obvious, or if I dodged an extremely clingy bullet. I've gotten different answers depending on who I asked.
