I need to break up with him...?

dont ever date out of pity thats the worst tihng one can do ... you don't seem like your so happy , you shouldn't have all this tension its not fair to you but u can fix it! the longer you hold on to it the more time will go by ,and ull be more stressed , i would say do it as soon as you can ull be happier when u look back to it in highschool ull also have a fresh start since its your last year... once you do it keep your friends close by this way it won't seem that bad with him have ur frds as a support system ... don't let him hold you back if your not happy leave now the longer u stay u hurt urself and him much more
