What can I do for my daughter?

I am a mother to 2 beautiful children, twins, named Nicole and Scott. Now they are 31 years old, while my son is living well, my daughter is not. My son is a lawyer and is married to a wonderful woman Jessica. They have 3 children and they are living in Des Monies, IA, and they are doing great. My daughter however, is driving me crazy! She is 31, a comedian, and is just now getting married.. To a guy that I do not approve of. He is a 44 year old director (at least that is what he says he is) who just whisked my daughter away to Los Angeles where they live together. How do I stop this wedding and get my daughter's life on track? I want her to have a good life. I want her to have children and be married to a successful guy that will actually love her. Jeff doesn't love her, if he did he would stop being a "director" and get a real job and support her. She needs to be at home and be a mother like Jessica instead of traveling to God knows where and telling jokes for cash.
