No. He’s done and he’s moved on. If you were arguing pretty frequently during the entire year you were together, it’s understandable that one or both of you would move on to try and find a relationship where there isn’t that kind of arguing. I know you want him back, but being in a relationship where you’re arguing that frequently isn’t healthy or pleasant. You’ll do better if you find someone with whom you don’t argue. It sounds like there were more than a few compatibility issues that led to the arguing and this is a great time to really think about what went wrong and why — so you can choose someone who’s more compatible next time around.
