<human>: Could you distill the essence of the text into 1-3 sentences?

Background: I've been seeing my girlfriend for almost 11 months. I still live with my parents, and due to outside circumstances, she lives with me in my room. Both of us are still in school, with me graduating at the end of the year. We plan on moving into our own apartment as soon as I am employed. 

I am her first boyfriend, and am the only person she has ever slept with. The other night, she mentioned that she was thinking of asking me about opening up our relationship. We talked about it quite a bit; it essentially boils down to me being the only guy she's ever really been involved with. Our relationship got pretty serious pretty fast as we became official about a week after we first started hanging out. She said that she didn't want to to do it because of wanting to sleep with other people, but because she wanted to experience "what she was missing" in terms of dating. Because of this, I asked if she wanted to essentially go on more dates with me, which she agreed to. 

I really don't want an open relationship because I get very anxious about her and I know that I would get jealous as soon as someone else became involved with her, so I see that as something that's completely out of the question. At the same time, I feel like I'm trapping her, what with her living with me and not being able to leave me without having to find somewhere else to live. That said, we really do love each other and have talked about marriage. 

Would taking her out on more dates be enough? I have absolutely no idea how to deal with this.
<bot>: Girlfriend mentioned the possibility of having an open relationship to be able to sow her wild oats (except not just for sex?). Don't know what to do.
