Though not always.... it seems like the BS has a lot invested when the A occurs... long-term Marriage, children at home, etc.. and they also seem to be the one strong and loyal ones - to the committment of the marriage and the family.
Therefore, they give the WS another chance and work hard (hopefully together) to make the M better, make themselves better, and keep everything together.
However, there is so much pain and so much hurt, I think it's really, really difficult to get to a really stable - and genuine and special love - that was there before the A (or at least in the beginning).
And by the time you figure it out that it's not as "great" as you thought it was going to be or what you were working towards - you've invested A LOT of time and energy into it - the rest of the family (children mostly I'm talking about)has pretty much forgotten about it - and you and your WS are getting along pretty good.
So... do you say at that point (years later)- I want more - I'm done with this M.. it will never be where I want it to be or should be.. so goodbye, sorry kids, I'm going to go out there and find something better. It feels like you're going to hurt everybody by doing that.
I think that decision sometimes needs to be made immediately... and move on... especially if you are in the early years of your M..
But there are great stories out there of how the M was turned around and it was better than ever.
And I think that's what we hold on to - and that's why we work so hard - with that hope... At least I do.
As long as he's not continuing to cheat, he is nice to me, he's trying most of the time, and he's respectful to me.. it's worth it (for now) to keep trying.
