<human>: We've been dating a year. Probably 6 nights out of the week she stays at my apartment. Quite often she'll leave dishes laying around, dirty clothes, etc. I've talked to her about cleaning up after herself and she says she tries. Right now I see a pile of dirty clothes on the floor in the bedroom, and her dirty work uniform in the corner of the living room along with a couple of dirty dishes she left sitting out.

She's clumsy, too. Lastnight we went to bed around 9. We get into my room and she spills water all over the floor. No biggie, it's just water - I grab a towel and clean it up. She's sipping tea in bed not long after and spills some over the sheets. A little annoyed but hey, accidents happen. I grab a towel and clean it up again. About 5 minutes later she spills the ENTIRE mug over me (burning my chest, it's sore and red today) and the bed. I had to wash the sheets while she used a hairdryer to dry the mattress. Didn't get to bed until 11 lastnight and I worked early this morning. Needless to say I was a little grumpy when I woke up. I was her ride to work which wasn't a big deal as we started at the same time and she's just 5 minutes past my work. Around 40 minutes until we need to leave and she informs me she left her uniform at home, which is about 10-15 minutes out of the way. I had to skip breakfast and work on an empty stomach today because of that. She's very apologetic and feels awful, and I get she didn't do it maliciously. Accidents happen and I understand that too. But with how many things happened in such a short duration, I'm still very annoyed. Going forward, how can I not let things like these affect our relationship?

Provide a brief overview of the text.
<bot>: Girlfriend is sloppy. Spilt tea on me and my bed. Almost made me late for work. Annoyed - how do I let it not affect us?
