I do agree he is wielding his weight as a weapon of control to garner sympathy and to hide behind. (Not as if that justifies anyone else being unkind about his weight of course) But I do feel aside from being very manipulative which is unfair to others, he is also not doing himself any favours in the long term. You can’t guilt a woman into liking you!
He keeps suggesting he usually does this great charm offensive which gets women to fall for him, hence he believes he will win Sarah round 🤦🏽♀️ But in the same breath has implied he usually likes woman a lot more than they like him - and ultimately they don’t really accept him or see him as special.
