am I wrong?

So I have been dating this amazing guy for almost two years now and we are 15. I turn 16 next month. But yesterday we got in an argument and it ended up with him calling me and telling me "we are done" so then he continued to tell me that he felt our relationship changing about 3-4 months ago and how he was waiting for it to change. But of course I cried and cried and cried for hours. But I went to my best friends house and I started feeling better. Then a few hours later in the middle of me feeling better he calls me and says sorry and how he made a mistake and how he wants me back.. I was thinking hard about it. And i don't want to lose him or his amazing family. And I love him so much. Was I wrong for taking him back?
