You think it can be awkward to have your roommate as your girlfriend but it's by far the better choice so, you tell Kacey : "- Option B. - Great !" You're now back in your house with you're girlfriend. You don't remember Kacey. The situation is indeed weird, however. You're not just a couple. You're married ! You never had sex together because you both remember that your wife was once a guy. You don't know how or when you get married nor, how your roommate became a girl. This situation is so weird that you may need to investigate. Or maybe you just need to do a couple therapie ?
