Should my 21 year old boyfriend be independent financially of his parents?

i sometimes feel like i can't stand my boyfriend since all the money he spends is from his parents pocket. my boyfriend 21 just exchanged majors and now he is back at year 1 , one of my first priorities is education but seeing my boyfriend starting just now while he could have finished annoys me sometimes because i expected a 21 year old to be independent already.

how can i stop being this way?
