I used to ask the same question. I used to think that there has to be people who stay in the relationship & the addict recovers. I would ask for advice hoping to hear just one person tell me "yes" and then I would be able to use that as my justification to stay. Just the same as in any situation, there are good outcomes and bad outcomes. I will say this though, my outcome was good, good because I got myself out of the relationship 5 years ago and work my program. Please take care of yourself and do what is best for you...you make your own ending.
