If a guy stops checking out other girls because you told him to what does that imply?

I was not comfortable with it and told him so and although he didn't admit it he looked embarrassed and was quiet the whole time. Since then he's completely stopped checking out other girls in front of me. Actually he's been making a concerted effort to stay away from other women when he's with me.
