<human>: Can you condense the text into a few key points?

We met 3 years ago and moved in together after 6 months. We live in an apartment with roommates and share a bedroom. She has always been someone who values her alone time and when she asks for it i give it to her by leaving our room for a couple hours. Recently, she said she'd like to have her own room. She feels like we spend too much time together and she needs her own space. She swears its not because she doesn't love me, but because she needs more alone time. We generally have a good time whenever we hang out (always laughing). 

Is this regressing in a relationship? Is this a bad thing and should I be worried that she feels tired of me and the spark is dying?
<bot>: GF moved in with me, we've lived together for 2.5 years and now she wants her own room. Is this a bad sign? (her own BEDroom)
