She was divorced and no longer wanted to have a relationship.
He said: Okay, let's not talk about feelings. I agree.
He followed the rules for a year and a half - no contact, no inquiries about his whereabouts, and ready to leave at any time.
But while she was drinking with others, he stood in the back alley of the bar and froze for an hour.
When she didn't reply, he wrote hundreds of notes about her habits in memos.
She said it was over and he left. Two months later, on Valentine's Day, he stood at her door:
"I just wanted to see if you were okay."
She said "come in".
He moved in again, and this time, she broke the rules herself.
