How would you feel if I told you that I don't want to date or be intimate with my bigger friend? If she were thinner, she'd be my perfect match
Really, do you have an issue with her being overweight?
She's way too big, I'm really uncomfortable with introducing her to my friends
It's wrong to judge someone by their weight like that. She may be big, but she probably has a pure soul.
I don't care. I'm just not attracted to my big friend
You just got through telling me she would be your perfect match so there is some attraction there. Don't judge her by her weight because in the end looks aren't what matters. Judge her by her character, which you clearly like already.
