I wouldn't worry about that. In my experience, open-eyed, non-naive is a lot more genuine, a lot more authentic, a lot richer, a lot more intimate, and a lot deeper.
When people do get to the other side of an A and talk about how much better their M is, this is why.
As far as quality of romantic Rs, there is certainly much to be gained through this process that leads to a place where better love is possible.
