I'll never forget the girlfriend who when I showed emotional vulnerability grabbed that knife and twisted it in the wound, telling me to man up. More painful than the immediate situation was the realization that I couldn't rely on her, that she was a fairweather girlfriend. Yes I broke up with her and yes I talked to a therapist about it. Never had a guy say anything like that to me. Other girlfriends have been there for me and were very supportive.
Maybe some parts of toxic masculinity are perpetuated more by women and the media than other men.
