Advice - help!

So my best friend of 10+ years needed a place to live for about 2 1/2 months and I’m allowing her to stay with me.

I live in a nicely sized studio apartment which is just about fine no issues with space at all!

However I’m finding myself tied between sharing my time with my boyfriend and my best friend. I’m giving them each my attention and time but I’m noticing that I’m not having any time for myself.

I like being alone and I like quiet. Both of them need attention and have their own wants but I’m honestly struggling to keep being happy and ready to do something with them when I can’t even sleep alone, eat alone, think alone or be alone. I never can just decompress and deal with my emotions anymore.

I feel like I may be selfish but they both always get upset or say something like “well so and so got 3 days this week what about us this time?” And I just feel like being pulled back and forth then also feel like I’m crumbling under my own thoughts.

Any advice?
