Am I supposed to give up on US?

So the problem is that my bf and I have been together for about a year and we were really happy. But sometimes he had issues with the fact that we couldn't hang out much during the summer because of my parents. So he decided that we needed a break or just to quit all together.. I don't know. Then he told me that we should go back to being best friends again because that's how we started out. And I was okay with that idea because we were most happy then. But then that same day I had to ask him for some money back I gave him the previous day. The money was supposed to be used to help our relationship move forward and we were going to go 50/50 on it. But then he broke it off the next day and he had offered me my money back before but I refused because money was never what I cared about. but a couple hours later due to my parents involvement I had to ask him for it back. He told me that he'd give it back but then he also said that this would be the last time we would talk again. and I just responded to him with kk because I really was in shock. So I think I might have made things worse because typically we talk about our problems but that may have lead him to believe I didn't care if our friendship was through. I told him that I was really really sorry for this. and he said yeah I bet you are. and "I told him well I am, I wanted you to keep it." and then he said "Just leave me alone. Please. Your parents are the victors that's all I'm going to say." The next day we met up and he handed me the money and I apologized to him again and then he just said "yeah.." like in disbelief or he had just given up or was hurt. and I tried to give him something else to show that I really didn't want to have to take the money back but he just ignored me and walked away. and I told him that I never meant for this to happen and he just continued to walk away. So I just said goodbye and left because I couldn't do anything else. What I don't understand is why he is acting like this. And what should I do. Sometimes when he is hurt he says leave me alone and I don't want to leave him hurting.. but hes just been so stressed about all of this and I don't wanna stress him out anymore because I really care about him. Please give me some advice.

Yeah we are 17. So pretty young I know. and because they are really religious type people so dating in general is a no. When we were best friends they seemed to like him but after we started dating they made it really difficult. Thank you for your help by the way.

Yeah we had previously talked about that and he knew that I didn't like the fact that we couldn't spend time together as often. and he decided that everything would be okay when school started again because then we could hang out often. But then the money issue happened the next day. I just think that I hurt him and I want to contact him and apologize because I never meant for this to happen. But then I also think that what if he just doesn't want anything to do with me anymore so who am I to take away his happiness. But its confusing because I don't understand how he could act so coldly after everything we had been through together..

And yes I agree, I definitely regret the whole money thing because I don't want him to think it was about that. Because it never was.
