Be single!! Youre 18 for Gods sake!!! and he is 17....there is no way in Hell he is ready for a steady relationship...His age is 17, he's more like 15 mentally....all guys are like that. As you go through your 20's you are going to change SOOOO MUCH!!!! Don't waste your time wondering if he loves you and why he won't cuddle...I know that is important to you, it's important to me too but he needs a chance to live and experience life and so do you, commitments are too messy at this age, don't stress yourself out!!! You'll be better off a single girl living a single life!! It can be so much fun!!!!!
