People that gain power in a relationship by believing they are better than another is always doomed to fail.
Whether you are athletic, naturally built to societies standards, or curvy and amazing, the thing that probably threatened him the most was your increased confidence.
Because with increased confidence with some insecure partners, comes the thought that they will have to level up to higher standards.
It is ironic to some as this is the opposite of those that nag (as we all know making statement about a persons body or weight never helps "ever"), but stealth commentary hits just as hard (and sometimes worse).
Why IMO ... dishonesty, but one will never know.
