<human>: I've been with my girlfriend for 3 years and we recently just moved in together. There's no one I want more to spend the rest of my life with than with her and I'm so excited that we have finally moved in together.

However, she has a friend who I've hung out with at a few parties already. Her friend is a really nice person and has a lot of the same interests that I have. I feel like I can talk to her about a bunch of stuff that we share in common and it makes me feel good.

Now I feel like such an awful person because I can tell that I'm interested in this person and want to keep talking to her outside of parties. I think just developing a friendship with her would be fine with me, but I don't even know how to go about it. I'm afraid of how I'm going to come across and I always imagine this whole thing blowing up in my face.  I contemplate sending her a facebook message and see how she responds but what would I say? 

I've already talked to my girlfriend about inviting her over so we can all hang out together but she doesn't seem to have an interest in inviting her over. I have told her that I am interested in becoming her friend and if she was ok with that but she never really gave me a direct answer. I believe she feels pretty strangely that I want to be friends with one of her friends and I'm not sure what to do or say about that.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I want to talk to my girlfriends friend yet I feel so guilty for even trying because I am attracted to her. What should I do?
