My boyfriend want's to pursue a career in animation but I think hes fucking terrible at art. I feel like I should discourage him from trying to make that his career path.
Wow I hope you are joking. Do you really feel that way?
I don't want him to be forever dependent on me. Animation may not be the best career choice if he doesn't get better at it.
I understand where you're coming from and it's a valid concern but rather than discouraging him from working on his art you should be supporting him while keeping expectations realistic. Let him know he's getting better but has a long way to go and make sure he keeps up a job and such while working on his passion.
That advice got me. I need to think about that.
Well I hope everything works out for you two. Have you checked into getting him the proper classes or maybe a private lesson?  I really hope you support him even the best animators were not vey good in the beginning.
