About Chloe...any "normal" mother would and SHOULD always have an deep interest in her child's future, whether Mom has only shared custody with Dad or even if he has full custody. So naturally it would be better for all concerned if Chloe took an interest in Dan's new partner, especially if remarriage with the new lover seemed probable. That does NOT mean that an ex-wife should be playing dirty and doing her best to sabotage the new relationship (like Chloe tried to do with Dannifer).
That was what my point was as well...of course she should care about her child, but simply not liking and trying to sabotage new relationships is beyond the pale. It seemed some posters were suggesting Daniel/Nicole aren't a good match because Chloe might be jealous or upset, and I don't think she should get to have the final say UNLESS she is concerned about Parker and can make a case for why it isn't good for him.
