I would suggest not becoming an actress. It is a waste of time to put all of your efforts into it. Why not get a real career and pursue acting on the side? In this case, you can still do something you enjoy while enjoying the financial benefits of having a solid foundation for a career. It's too risky and to put all of your efforts into something like acting.

If you're willing to put in a lifetime of commitment to a person, then why not marry him or her? There are plenty of benefits outside the actual declaration of commitment itself, such as insurance benefits, tax benefits, etc.
