The whirlwind.
You've been on four dates in eight days. He calls you his girlfriend on date two, books a weekend trip on date three, and is hurt when you want to see your friends on Friday. He says, 'I've just never felt this before.'
"I'm enjoying this, and I'm not going to skip my friends. If that's a problem, we're moving at different speeds."
If the speed doesn't normalize after a clear conversation — or if you're punished with silence or anger — treat that as the answer.
