<human>: Hey, so when me and my girlfriend started dating we became basically 'best friends.' In the last year, she met and became very good friends with a girl, probably now they get along better then me and my girlfriend do. Thats fine! But its to the point I really don't like hanging out with them two, because when we double date me and the other boyfriend are pretty much ignored.

Basically, she's much more excited to tell her funny jokes, her big news, and gossip with the friend. I don't think I would have as much a problem with this except that she used to want to share all that with me.  Its caused me over the last three months to feel much more distant then we were before, and I don't know that she has particularly noticed, or if she has she doesn't know how to handle it/talk about it. I almost feel like breaking up, except that I feel like I still could like her a lot.

Summarize the given text in a few sentences.
<bot>: i think i just want to hear about how you deal with dating someone who has a best friend who isn't you.
