Hmmm. You called her ugly dat’s mean. Why don’t you motivate her to loose weight instead of thinking all this about her?. After all she is your friend.
I just met someone quite obese at gym and i tried my best to motivate her to loose her fat NOT cuz of finding a guy who would like her BUT for health reasons. 140kgs is omg too much She should be less than half of this. It will be a hard task but you have to start from somewhere.
