The first night, I asked for a kiss, she flirtatiously said "OK, but just one," we stretched it to some length, I was happy, smiling. She seemed so tired that I let her roll over, and while I scratched her back she said, "You smell good." We slept tightly cuddled.
The second night, I asked for a kiss, she gave one, but cut it short, rolled over, said goodnight. We slept tightly cuddled.
The third night, she turned away with a jerk, without a kiss, and we slept with my arm on her hip.
The fourth night, she kept her distance, and from then on we slept without touching.
Through this trajectory we talked about it not at all, so that I left confused, and dismayed, and this confusion contributed a good deal to my sudden deep depression at home.
