Not that I condone adultery, but Crys and Pietro's marriage had problems before the affair so his behaviour was partly responsible for what happened. Ronan, on the other hand, was entirely blameless for what went wrong between him and Crystal--it was imposed on the outside from her family/king.
The other thing that muddies the waters a bit with the Pietro/Crystal mess is that it has been said that Maximus had influenced both of them to cause that whole incident--so to what extent Crystal (and Pietro) were responsible for their actions is unclear.
In any case, just because Crystal feels guilty over what happened with her and Ronan doesn't mean she doesn't feel badly about what happened with Pietro too. We know from many past stories that she does--and has apologized and tried to atone. For the most part, they've made their peace with that whole situation over the years. Nowadays the rifts and tensions between them are more about his post-House Of M actions when he abducted Luna, stole Terrigen to try and restore his own powers, etc.
