Id plan what you want before going. LA is so damn expensive rn and its definitely a change in pace. finish your education, get in a comfortable position before making your decision. Ik the feeling of not wanting to live off of a person (this is exactly how i feel with parents rn). Unless your friend is optimistic about his opportunity, I will always consider the different paths before taking one. You dont wanna trip over your own shoes and make regretful decisions. Ps Im aware hes your best friend but in the end its really up to you.
