I fuckin hate showering with my girlfriend

My girlfriend has been a bit clingy recently. She follows me around the apartment and doesn’t really give me any space. I just want some fuckin alone time and everytime I go to shower she wants to with me. We’ve been dating a year and at first it was sexy but she just does it to spend time with me but we spend all our time together and in the shower we have to keep moving to get the water on us and it’s so annoying. I found myself purposefully jumping in the shower as soon as possible if I find out she’s coming home a bit late from work and giving her the excuse that I’m shaving so she can’t be in with me. Does anyone else have this problem? And yes I do expect a bunch of people hating on me and just being happy that she likes me at all yadda yadda yadda
