I know it makes me seem shallow, but I don't want to date someone that's overweight.
Why are you judging people based on their size?
I don't feel comfortable around fat people
Sometimes you can't help who you are attracted to but you shouldn't not date somebody because they are overweight. People are more than their weight and even people who were skinny when you started dating can get fat later in life. People could shame you for not dating fat people.
I just don't think I'll ever be attracted to someone that's overweight.
You have to look past people's appearances because what they're like inside is what's most important. It could really hurt other people's feelings to be judged for what they look like and not who they are inside.
