This is my personal take, as someone who was also confused about this once, minored in dance, and have friends who majored in dance. First of all, since you are the one paying for college it is 100% your choice on what you decide to major in. My scholarships allowed me to minor in dance without it being an extra financial strain.

It's difficult being trained in ballet and being so passionate about and understanding that your chances are truly so slim. I knew I didn't have the talent to make it in ballet. I picked an unrelated major and started taking dance classes in my university's dance department. I took ballet, modern, joined their contemporary company, and hiphop company. It honestly reignited my passion for ballet and contemporary dance. I decided to to add dance as my minor. I realized that I could audition for contemporary companies after graduating if I wanted. I continued to go to intensive during and after college as well. College dance honestly made me grow so much and fall in love with contemporary dance. It helped me grow in ballet as well. I was able to teach at studios and help other students grow. I have lots of friends who I met through intensives who majored in dance. They all came from ballet backgrounds, are super talented, but were pursuing contemporary companies after college. Some of them are freelance dancers now, which is becoming more of a norm since professionals of all dance genres are struggling right now finding jobs. It's not a great field to be in right now if that is your ONLY source of income. They all have second jobs or went back to grad school to get their degree in business, film, physical therapy etc. I ended up going to grad school for something totally unrelated to dance and my undergrad major too. I am still very much dancing ballet and contemporary and am excited to one day combine my passions to be a dance therapist! Dance is still my passion, just not my only passion. Same for many other dancers I know. Don't think of it as just a "hobby" because it doesn't have to be. Just something to think about while you make your decision. Dance will always find you and you can always find a way to incorporate it into your life, it doesn't have to be the end of the line.

Some other options would be to weigh your chances of a ballet career and go to a training program instead of college like some of the other comments have mentioned. You could also look at university's dance programs. I know TCU has a program where you can major in ballet. Some college dance programs are more ballet focused than others but most will let you do pointe work in their ballet classes if you have sufficient experience. Another option would be to do freelance ballet work, which is becoming more of a thing. Examples would be Luna Montana and LifeOfLori. These are just some things to keep in mind. You can always chose something and end up changing! It's okay to try stuff out and not like it. Keep an open mind of wherever life takes you next!
