<human>: Can you give me the gist of the text in a nutshell?

My friend "Rachel" and I tripped on Saturday and my partner Marie was not with us but Rachel kept getting my name wrong and going "Right, Marie?....! I mean Anna! Mar-Anna! Yay, Marie  I mean Anna!" Etc.

 And anytime I touched my phone it was like"what is Marie up to? What's she doing? How's the jazz festival going for hey? " etc. And it makes me really uncomfortable and I don't know what to do. I am pretty sure she got my name wrong more than right. 

The main reason this is an issue is that I am always scared that people are using me to get closer to Marie or be around Marie because she is bad at remembering to talk and plan things with people.

We are a poly couple but I am uncomfortable having my company be used to get closer to Marie, and not for the sake of my own relationship.  The being incredibly interested in my partner thing had gone on for awhile and when Rachel and I talk Marie is a constant subject she brings up. Marie like her as well.  They are both trans women, and I'm scared I'm mistaking this all for something unpleasant when it's just solidarity in a demographic?  I dunno. 
Please help, do I address this directly or what?
<bot>: friend kept calling me by my partner's make keeps asking about partner,  and I am concerned they are using me to get closer to partner instead of being interested in being friends with me personally.
