I want to quit university to be with my love
Quitting university for someone seems like a bad idea. Are you sure you want to do this?
I've always wanted to be an actor, if I don't do something about it now I never will.
I get that you're in deep love, but it's never worth giving up on your dreams for a partner. They may not be with you forever, and you may regret shirking your education for something so temporary.
I don't care about any of that. She's all I've ever wanted. If I miss out on one moment of life, I can't take it back. I know I'll regret it but I'll make it all up when I become famous for my acting skills.
You're making a lot of assumptions about your success without anything to back it up. Having an education as a back up is a good idea since not everyone is capable of becoming a famous actor.
