Anti social a bad thing ?

Okay so I'm in high school and I don't really mess with anyone except for like 3 girls and my boyfriend . I don't like the school & I have no motivation for it. I come to class and be quiet and not say a word. My teacher decides to tell my boyfriend that he can't pin point if I'm mad, depressed/sad. My boyfriend told him that I was anti social and he says how does a social person & anti social work out together because the social person would have to end up taking care of anti social person because antisocial people tends to want attention on them 24/7 and get mad at every little thing. He asked if I was on meds and I needed therapy . I don't agree with him on this & even if I was antisocial how is it a bad thing ?
