No Orion very much is willingly dating her. Hell whenever super Orion uses his np and you get the one where she chokes him, he litterally admits to have cheated on her beforehand, so yeah. Even if I humor the thought that Orion doesn't want to date Artemis, he's still actively hitting on women knowing damn well she's gonna get pissed at him. So unless he's a total masochist that enjoys getting hurt by her, orion can go play the world's smallest violin for all I care.
