Tinder is wild

I will never again hang out with someone i met on tinder. After a couple of dates. We had a chill night at his place. Which was fine. Except the fact that a couple of days later he tells me he has head lice. Which isn’t common in African American people. But proceeded to tell me. He knew his head was itching and bleeding when he washed it. But he never believed that black people could get lice. So he just assumed his head was itching bad. And he DEBATED telling me. Because he figured I wouldn’t get it because im also African American. My head doesn’t itch or anything. But how tf do you check for lice ? Am I a jerk for blocking him immediately after the phone call. He made it seem like its not a big deal. But to me it is.
