Needing Advice.

I need help with a lot of things. But the thing I am asking now is about my boyfriend. We have been together almost two years and we are just not doing well. I'm only 17, he is 16, and I think we have burnt out. I love the guy but it's just not working anymore. We have talked about a break and I know that breaks usually don't work. So what should I do? If you need more infomation you can message me.

Also I am starting to look for other people. I don't want to spend my senior year in highschool with the same guy, but I also do. I feel comfortable and safe with him, and I'm terrified to be by myself.
