<human>: So, we've been together for 6 months, and we live in an apartment together. She gets home from work at around 1:30 p.m. and I get home at around 4:30 p.m. She works the morning shift at 5 a.m. 

So, it snowed a lot while I was at work - blizzard conditions. I was driving home when my car slipped on ice/snow got stuck right to the side of the highway. My phone was dying, so I immediately called my gf who didn't pick up her phone. 

I left a voicemail saying that I was stuck and would probably have to call a tow truck. Call me back when you get this. I wasn't getting a call back so I dug myself out for about 30 minutes. Then, I hit the gas at full force and finally got out. 

So, I get back to the apartment and my girlfriend is sleeping. I wake her up and say, "wtf? I called you. I needed you and you're sleeping." Her response was, "I went to sleep at 12:30 am. I can sleep when I want to." 

She's usually not like this, but this made me upset. Is this what destroys relationships or am I overthinking? I'm not sure what to do. I mean I relied on her for something and she was sleeping and didn't even feel guilt about it.

Summarize the given text in a few sentences.
<bot>: Gf was sleeping when my car broke down next to a highway in the snow. I had to dig myself out and pray that I could get out because my phone was practically dead.
