What should I do?

So I have a curfew at 11 and I didn't get home until 12:20. Yesterday, this is what happened



Yesterday there was supposed to be a meteor shower and I was going to was it with this guy I'm seeing. I don't get a signal at the water and my phone died, it was too cloudy but we were at the water and it was nice and relaxing so we stayed, I ended up falling asleep and so did he, and he woke me up at 12:20 telling me I had to go home.



The dock is near my dads house, not moms (divorced parents) and Mondays I'm supposed to go to my dads, so I did, but for some reason I was supposed to go to my mom when I didn't



My mom sent my bf a message at 12 asking where I was, and he replied, telling me he dropped me off at my dads



My twin told me my mom was mad because I didn't come home



And my mom sent me a text this mourning saying "if you can't manage to come home before 11, maybe you shouldn't be going out at all"



I tried to explain to we it was an accident but she's a no none sense type person and thinks people should go strictly by the rules.



What do I do? I want to still hangout with my bf.
