How could he have meant those kisses and why was he using a blanket even though he didn't need it?

My trainer, colleague and friend was getting ready to go on an off-road trip in the mountains. In the morning at work I wrote to him not to go home after work, that I wanted to give me something. When he left a little early, he announced that he was going home. So I wrote to him to wait and that I would come to him right away. We exchanged a few sentences, he initiated pleasant kisses on the cheeks, I gave him a warm blanket, scented with my perfume, for the trip. Finally, I told him that I would miss him. He told me that he would only be gone for a few days. I wished him a safe trip and that he should enjoy it. In one of the photos he posted, I saw that he was taking the blanket off me on the bed in the car. What do you think about that?
