<human>: Can you condense the text into three sentences or less?

So, I've been dating my girlfriend for 10 months, and things have been going great recently. My main sport happens to be basketball and I'm going to play in college, however that means that I will have limited time to spend with my girlfriend during springtime. 
   
 I want to audition for the play tomorrow because it is my senior year and I always wanted to give acting a shot. My dad went into the acting business in LA and would involve me in his own plays when he was in charge of drama at a high school when I was 7. 
   
She doesn't want me to be in the play for a couple of reasons: 1. This fall and through November is the only period where we could hang out every day without a schedule conflict. 
2. She feels uncomfortable with me around other girls in this play, and feels like I would never hang out with her after rehearsals. 

   She has been really unsupportive, and it means so much to me to audition and at least fulfill this small dream of mine, but we constantly argue about it. I keep asking her for better reasons, but she says that she can't help how she feels and that she knows its clingy but she can't be supportive. 
I don't want to break up, but I don't know how to reassure her and stop her insecurities. What should I do?
<bot>: Girlfriend doesn't want me to audition and spend time away from her. I don't want to end up having regrets in high school.
