We are both in our 50s have been together 5 years and married for 2. We have a great life, fantastic sex life and he is a wonderful step dad to my two girls. I have known him most of my life so I know who he is and what kind of person he is. I'm completely confident that he is a faithful man and not at all lecherous. I've never noticed him looking at women when we were friends but since we've been together I have noticed that if there is a young woman in a tight skirt or leggings I can be pretty sure he will take a look at some point. He's not staring or ogling but certainly registers that they are there. The first time it happened really noticeably I called him out on it and he denied it emphatically. We've had the same argument a few times and each time he tells me I am wrong and that he just generally looks around and sees everyone equally. He is really distracted by movement when we are out and it is true that he will be aware of what is going on at another table in a restaurant etc. When I have read threads like this before the responses are always to talk to him and tell him to stop. However, I don't know what to do if you raise the subject and he denies that it is happening! I think he genuinely believes this, but the problem is that I genuinely believe that he is doing it! I feel really embarrassed when it happens and know what everyone around us would think if they saw him. We are really happy together and have a good, honest relationship, but this one thing really bothers me. It is at the point where he knows I am watching him when we're out and it makes him feel on edge too, so we are both uncomfortable. AIBU about this? Should I just relax and accept that it is only a handful of times and is meaningless? Are there any men out there can put this into perspective for me?
