I see your point sweety but I also think you know the answer.

You're not on trial so you aren't obligated to tell the truth, the whole truth, and nothing but the truth.

How about putting it out there like this..."I'm not dead so of course I look at other women. That doesn't make me want to leave you. I just look. It's only natural. You look and you haven't left me. Ours is a deeper relationship than the superficial. I know you inside and out and I am where I want to be. Please stop trying to push me away when we both want to be together. Your beauty isn't just physical. I'm not as shallow as that. I love you for all of you!"

Or something like that...

Good luck!
