My husbands passenger seat is always pulled back, could he be cheating?

So everytime my partner works overtime, which is the whole 7 days, i always find the passenger seat being pulled back. Pull back to ther point where i can fall asleep, but just not as far. Plus its pushed back. Could he be cheating on me? Im thinking this way because i remember when we were still dating, i was sitting on the passenger seat, and he pulled my seat back, and we made out. I don't know maybe im just thinking too much? But how can the passenger seat be pulled back like that everytime he works 7 days a week? When he was working at his old job, the passenger seat was pulled back too, but it was only once, and it wasn't pulled back to the point where i can lay myself to sleep. I ask him and he said it was his coworker buddy. But that was his old job, now is a new job, and i notice it happens everytime he works overtime for a week.
