I love my girlfriend, but I'm not as attracted to her as I am to other women due to her being overweight. She's amazing to me in every other aspect, she supports me, has an amazing career, we share hobbies, she's basically my best friend. Despite this, I can't help finding myself wishing that I was with a more attractive woman. What do I do? We're in almost a year and a half now and the feeling has only gotten stronger now that we're out of the honeymoon phase. Am I a piece of shit?
