What do I do in this situation? ?

Any time my boyfriend thinks that a girl is attractive, I instantly know. It’s fine that he thinks other girls are attractive, but when it’s right in front of me I think it’s rude and makes me feel invalid. For example, every time we go through a drive through he is always nervous and talks in this nervous high pitched voice. The other day they were taking orders outside the drive through. When the girl took our order outside the car, I instantly knew he thought she was attractive because he forced this deep manly voice and tried to sound good for her. He never ever talks like that. When I confronted him he said “I didn’t know I was doing it, I wasn’t doing it on purpose.” Another thing that he does that bothers me is if we have the tv on and hes on his phone, every time a girl who sounds attractive starts talking he immediately looks up at the tv to see what she looks like. It bothers me because it happens so often, and it’s right in front of me! It makes me feel like crap. This just happened, and when i was annoyed with him he said “I didn’t do anything wrong.” I don’t know what to do in this situation
