should I break up with my boyfriend

Christine
So I've been in a relationship for 2 and half months now. And it's been great but recently he's been working a lot more than usual which means we don't get to spend time together and whenever we do it's less than an hour. We've argued quite a few times about it but I know that I can't make him quite his job but he's just not understanding my point of view and as well as that whenever he is free he never tells me I find out from social media he is out with his friends and he lacks in communication big time. I feel like I'm nagging him so much and he's lost interest in me and i just don't know what to do.
Do I break up with him or do I stay with him and try to fix our problems?
I'm 16 and he's 18.
