Most Helpful Girl
You can't expect him to be attracted to you and only you for the rest of his life. He's human, of course he's going to find other girls attractive just like I'm sure you may find other guys attractive as well. He's treating you perfectly it sounds like and you need to just push all of the bad thoughts aside and realize that he's with you and wants to be with you and only you. Until he gives you a reason to not trust him, then trust him because it sounds like he earned it. Its okay to let someone that you find so perfect in. Appreciate him and not think the worst.
