Well this is mostly mental health forum. If someone posted on here that they have eating disorders or whatever other weight issue, you wouldn’t berate them. You’d likely use a different approach. This person isn’t even posting here and OP was asking about attraction to him, not if this weight is healthy. It’s established it’s not a healthy weight and it sounds that both OP and this man both know about it. Typically people won’t stop unhealthy behaviors if they are told they are being disgusting. It doesn’t work that way.
