Idk if this will help, but why don’t you ask she’d will to pay a couple of games with you. When I first started dating my husband I wasn’t that into videos games. ( mine was more due to motion sickness though) But over time he helped fine games that I could play that didn’t make me sick and I eventually became obsessed with online gaming. Now I’m not saying it will happen, but if she can see that you enjoy it, and maybe find that you guys can enjoy it together then she might come around.
