Balancing Dreams in the Journey of Love

I was chosen in every acting audition I attended. My girlfriend always said she didn't want me to pursue acting, so I stopped and focused on my business. I married her, but later felt unfulfilled; I longed for acting. Therefore, I enrolled in a media school, but she began expressing insecurities, fearing the attention fame might bring and the potential attraction from other women. She has completely changed, even threatening divorce. I want to pursue my passion, but I also don't want to end our marriage. What would you advice the man to do?
