Make it or break it? Pig & Monkey

I was born in year 1992. My boyfriend, on and off, born in year 1995. We've been together for 2 years and we're usually great together but our fights gets bad to the point of no respect for one another (put downs, blaming one another, cursing, etc). I have a problem of trusting him when he hasn't done anything wrong (not that I know of). He blames it on my insecurity to why the arguments starts randomly. I love him and maybe I'm expecting too much from him because he doesn't know how to communicate or get into contact with me while I'm away working in Jersey (texting, calling). I always have to be the first to contact him. We're currently on a break and he's going down south to work for the summer. Should I be concerned with him messing around with others? Is this relationship done for good? Should I let it go completely and move on to save tears?
