It is in no way shape or form toxic masculinity to want to be in a monogamous relationship. It is also not toxic masculinity to expect your partner won’t bail to screw other dudes, or think that your partner pushing for an “ethical” non monogamous relationship after years of monogamy is anything but ethnical.

We wouldn’t even be having this conversation if genders were flipped. You’re basically attempting to weaponize feminism to justify the mistreatment of men.
