Most Helpful Girl
If the fighting was about small things that can be changed, fixed or forgotten about, tell him you want to give your relationship another go because you think it's worth saving. If you guys have real issues that you can't see ending any time soon, maybe it's time to let him go. It's normal to miss him and worry about what he's doing with other girls, but don't let these early feelings cloud your original judgement (which was that you both needed time away from each other).
I think the bottom line is that you need closure. Whether you decide to let it go or try again, you'll need to have a conversation with him so you can let each other know where you stand and then come to a final decision.1
