<human>: My good friend (let's call her Taylor) and her friend (Amber, also 20F) recently moved in with me and a group of my other friends (20-21, M&F) this past year (two of which live in our apartment and the rest live next door in the other apartment). I was very apprehensive at first about all of us living together since my apartment friends tend to be rowdier than Taylor and Amber and love to have a good time, but I love having them as friends nonetheless. I'd also only spent time with Taylor and my apartment friends separately, but Taylor had been wanting to become friends with them for some time. 

Fast forward to a year later (last Friday). Taylor and Amber both think very little of most of my friends at the apartment and do not consider many of them to be friends of theirs. Taylor has mentioned several times that she thinks they're manipulative and take advantage of other people. She says I'm different around them, that she's "disappointed" in me, and that I can do better (which was a little harsh, in my opinion). I know this is all coming from a good place, and I have expressed some of my frustrations with my friends to Taylor in the past, but I would never consider giving them up as friends. Taylor is also the sort of person who cares deeply about her close friends and I'm lucky to be one of them. I sometimes, though, think she can be a little possessive, but a good friend nonetheless.

Next year, my two friends (not Taylor or Amber) are moving out, and two of Taylor and Amber's friends are moving in, which actually has the potential to work out really nicely. I'm wondering if, from here on out, I should keep my two different groups of friends completely separate in my life, as everyone coming together hasn't quite worked out yet. I'm still trying to figure out a way to approach Taylor about all of this. I'm a little hurt by what she said to me this past Friday about being disappointed in me. I feel like I'm stuck in the middle and it's hard to find a balance without offending or upsetting Taylor. I've spent all weekend stressing over this. Any advice would be greatly appreciated.

<bot>: Friend hates my other group of friends and doesn't like that I spend time with them, acting possessive and says I'm different around them, how do I approach the situation?
