Can our marriage still be saved?

In 2008 my former husband of 14 years walked away from my life and we've been separated ever since. We have always been together sexually and both have experienced sleeping with others. I stopped because I wanted my marriage to work out but he did not. If he stops sleeping with other women, can our marriage be saved? Or should we just part ways? I still care deeply about him after all that I did and he has done. But he is seeing someone else on and off for years now. Will our marriage still be saved if he decides that he wants to try to do so?
