Emma, relationships can be confusing. You said yourself that you don't want to be together with him forever. People at 17 can be really confused. If he has a problem with holding your hand suddenly, it might be because he feels like it is a mandatory thing to hold your hand, and he might be trying to rebel. and just becuase you get into a fight and he doesn't break up with you is not definite proof that he loves you. (I'm not saying he doesn't) It might just mean that he wants to think about it when he is feeling more clear headed. Well, every couple has their arguments at times. But at 17 things are a little bit more random and immature.
