well, 1) said boyfriend was Poseidon so eff you Poseidon for your petty rivalry with Athena (even though I sort of ship those two gods),

2) if the do was consensual i totally despise how it was only medusa who got "punished" but yea what were you thinking Med to screw around in the temple of a VIRGIN GODDESS?!

3) there's a version in which medusa was arrogant about her beauty (her hair to be precise) and compared herself to Athena when she attracted Poseidon, in which case, yes she had it coming even tho it might be a bit too harsh in modern standards,

4) a totally popular version know to the mass is that she was raped by Poseidon, in which case eff you both Po & The!,

5) there's an interpretation/version in which Athena's "curse" was actually a "blessing in disguise" and i like the sound of that, and is possible since Medusa later used as a symbol of protection for women; not to mention Medusa means "guardian" or "protectress"



a lot of the greek & roman myths have more than one interpretation, and it's our choice to have a preference and preferred "canon" but we honestly need to be a bit open about what's "true" in those myths. it's more confusing than any other myths i've learned due it having a rather unspecified origin and whatnot
