Keep it neutral and ask for her story first

“Well, do you want to tell me something?” you ask, “and this time I won't accept it if you back off again. You almost killed me, I think I deserve the whole story.”

“Y-yeah you're right,” Jenny agrees and sits down next to you, “ but first it's very important for me that you know I didn't attack you on purpose. When I'm in my werewolf form I can't control what I do. As you probably figured out, I'm a werewolf. You might think this can't be and to be honest, I also thought that before I was infected. One night I was bitten by another Werewolf and since then I change into a monster every fucking night.”

“So you can't decide when to change?” you make sure, “and you can't control what you do when you are a monster. Not even a little bit?”

“No, I can't,” Jenny answers and sounds very sad, you even see tears running down her cheeks, “I can't control anything. And I don't remember much. Sometimes I see a few fragments of what I have done. Like a nightmare but I know it's real. The closer the new moon comes the more I can see. And for a few days per month, I can perfectly control myself. But that's only five or six nights in a month. Every other night I'm afraid of the rising moon. Because if only a small thing goes wrong I could wake up in the blood of someone I love. Like you.”

“And … for how long have you been like this?” you ask nervously, “we … we had sex a few times. Was this dangerous for me?”

“It's not an STD,” Jenny ensures you, “it's more a curse than an illness. Only if I bite you in my werewolf form and taste your blood you'll get infected, well most probably. There is no other way to spread this. And in human form, there is no danger for anyone. You remember the day my mother left me and we became a couple? About a month earlier I watched the stars in this forest with my parents. I left them for a moment to pee when I was suddenly attacked by another werewolf. I know now that he couldn't control himself too. But what's more important is, that I was bitten by him before my father could scare him away. They brought me to a hospital and then the worst night in their life began. I changed to a werewolf for the first time. I tried to kill and eat my own parents. It was pure luck nobody got hurt. The following days they often argued about me. They didn't know who they could ask for help. For my mother, it was too much and she left. I was small back then and they could lock me in my room for the night, but as I grew so did my werewolf form. To be safe they had to restrain me overnight.”

“How do they manage? I saw you slicing massive logs with no problems. What could restrain you?”

“My strength as a werewolf is not unlimited,” Jenny answers shyly, “I can be stopped by steel and other tough materials, and there is also silver. I don't know why but it has a special effect on werewolves. It's like burning coals or... concentrated acid.”

“I see,” you mumble, “this explains why I could defeat you with a belt buckler made of sterling silver.”

“Yes, I … have some memories about me touching silver,” Jenny mumbles and blushes, “in human form, it's not a problem, but as a werewolf, I can feel burning pain if silver comes too close to me. If I touch it, it burns my flesh.”

“So you've … lived like this since we were in elementary school?” you ask and begin to get upset, “why did you never think you should tell me?”

“I … I couldn't,” Jenny says crying, “the day my mother left I realized that I will never have a normal life. I could never enjoy what others see as normal. No sleepovers with friends, no partying till midnight, no firework at Sylvester, no dating, and most importantly not even a complete family. I never showed you my room because there is a massive cage. I spend almost every night there to not accidentally kill my father. Every night I change in this monster and slaughter everything that gets in my range.”

“But we dated for several years now,” you say loud, “I made plans for a future together. When did you plan to tell me?”

“We dated only by daylight,” Jenny explained, “and I didn't know we would be together for so long. I love you. I really do. You are one of the few last things that make my daily life a good one and give me a reason to keep on. Every time after I enjoyed being with you I felt guilt because I know one day I would have to find a reason to break up with you. There is no future with family for a monster like me. I'm too dangerous. Often I thought about just end my life. Two times I was at the top of the college and thought about just jumping and end this nightmare. But I couldn't. Because of you and my father. He could have improved his career but he didn't because he had to take care of me. I couldn't do this to him or you.”

“You thought about suicide?” you ask shocked, “really?”

“Of course I did,” Jenny cries, “you can't imagine how it is to live like this. It's not even a real life. Living in fear to rip the ones you love in pieces. Putting innocents in danger just by existing and the knowledge that you love someone but could never be with him. The same horror every night until I die someday. There is no cure and no hope for werewolves. And the worst is, I knew that someday my secret would be revealed. I knew I couldn't hide it forever. I knew that someday I would have to tell you and break up with you. I … I just hoped that it would last. It was a silly hope.”

“Wait you … you want to break up with me?” you ask confused, “after all that happened you just want to end it?”

“Don't be ridiculous,” Jenny replies in tears, “werewolves don't have relationships like this, there is no way a monster like me could have a healthy relationship or a family. So … do yourself a favor and look for a new girlfriend. One that isn't a wild predator.”
