How can I get my mom to an understanding and agreement?

Okay so…Back in fourth of July I had 2 issues, the 1st one was solved, but the 2nd one is in the process. The first one was that my mom got mad at me for not telling her that I was going to hang out with my girlfriend for the 4th of July. But I was gonna tell her that day, since I found out late notice, and I was able to go with her to be with her. But that led to my 2nd issue….The issue was that while I was over at my girlfriends house the pier closed so we couldn’t see fireworks, instead we saw Transformers Dark side of the moon. And we had to take the LATE show which was at 10:00 and didn’t start till about 10:30 at night. So we went to the movies and saw the movie and we didn’t get out till about 1:30 AM…And my mom works as a flight attendant and she had to go to work in an hour… And she was up all night looking for me since I didn’t answer my phone since it was on silent and turned off the vibrations. She went over to my girlfriends house and confronted the mom that was there and there was a lot of drama and my girlfriend and her mom don’t have a very good connection and her mom apparently didn’t hear that I came over and told my mom that she didn’t know I was there, and neither did the father… But I was with the father and girlfriend…

There was more to when my mom went to her house, but she was about ready to call the police…But when the movie ended I texted her that I just got out of the movies.

But the issue is that I’m dealing with right now is that she won’t let me go to her house to see her… But she’s blowing this out of proportion to me, since I was in a movie, my phone was off and it was long movie, which I wasn’t expecting I was hoping it would be like…an hour and a half movie or so…but it came out to about… almost a 3 hour movie to me. And I’m not sure what to do so I can go see her at her house… She can’t come over to my house sadly since her mom won’t let her.

And also another thing with my mom, she’s a hardheaded mother, and she can be stubborn and she yells and gets mad easily. Plus, she also thinks that her parents will do something, like child pornography, or touch me inappropriately . But I’ve been to her house a lot and I’ve stayed with her since I’m only with her, and her moms usually gone at work, and the dads upstairs along with the brother…

Sorry for this being so long everyone! But I just don’t know what to do…And it’s my summer break too! I shouldn’t have to go through all this trouble just so I can see my girlfriend since it’s my break… I should be jumping through hoops when I’m in school and dealing with my homework! But Fluther can you please help me, we really miss each other, and all this is just insanitary to me.
