Unfortunately, when there's not a lot of binds (like long-term marriage, children, etc...) it's much easier to dissolve it and move on. Unless there is more connecting you it will be difficult to bring it back together. You can try starting up a friendship... and perhaps that can lead to more. But I have to warn you it takes a long time for people to work through affairs. Even in a long-term marriage with children it's REALLY HARD to piece it back together. You have to realize that even if you get back together he'd blame you and be angry about this for a long time (years!!!!). It's a rough road.
There is no arriving, ever. It is all a continual becoming.
