<human>: Well I (male, age 26) finally moved in with my girlfriend (age 24) of two years last week! So everything is going fine and we are learning our boundaries and such, however last night my girlfriend said she has her best friend coming over this Friday. I said "that's great. Im glad you get to see your friend and what not". She then proceeds to ask me if I had plans because she was going to be up late with her friend do face masks and drinking wine and there wont be a place for you to sleep unless you're okay with sleeping on the couch......... I was really taken aback by this statement because this is our home now, this is our bed and I don't think her friend should be sleeping in our bed and me being displaced in my own home.

so reddit I ask. How should I approach this topic with my girlfriend and is this okay?

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend is having her best friend come over for a girls night. Wants me to sleep on the couch because her friend will be sleeping in our bed.
