<human>: Hi everyone,

My boyfriend of 7 years wants his best friend to move in with us. 

We were long-distance for a very long time, and have only been living together for about a year. It's been great!

We previously lived with the best friend, but best friend wanted a change so basically told us to find a new place. That was ~5 months ago.

I love the privacy I have in my new place. I love that I have my "own" place, that I can decorate to our liking. We had plans to create an exercise room with our spare bedroom. The best friend gets along with both of us, and he is a good guy.

What makes me angry is that my boyfriend accepted the best friend moving in with us without even asking if I was okay with it.

This puts me in a really awkward position now. Best friend is geared to move in by next month. Besides that, he wants to rearrange our entire living room, making it essentially his own gaming area. I was playing off being happy about it, but really am not comfortable with all of this.

I REALLY don't want him to move in, but feel like an asshole at this stage, because he is already planning to move in by January.
My boyfriend is out of town for a few days, so I'd like to get some advice on how to communicate this issue with him.

Can you give me a shortened version of the text?
