Broke up with boyfriend of almost 4 years?

All relationships hit rough patches. And four years is a pretty good amount of time, especially when you're only 20. I don't think you should throw this to the curb just yet, I think if you really want to be together that you will push thru the arguments. Every couple has problems but it's about facing them together and getting thru them as a team. If you guys seem to have a hard time doing that and you think the fighting is slowly tearing you apart, maybe just move on. But I think it's something to work at since you've been together this long and you clearly care about each other.
