She will have to speed up with her plans to break the two sisters once and for all. They can't stay united like this; it's not good at all for her.
And just because this David is in the picture doesn't mean temptation can't happen. She won't give up and will put more effort into her foolish son to go all the way and do whatever it's necessary to get his cousin's attention.
Cheating breaks couples right? How about another dose of that and she will see if the boy will still stay with her?
Esmeralda was cheated on and that's why she is not with Elias anymore, how about she also cheats, and then… the boy won't be with her anymore. And there her baby will make his grand entrance. Imagine this, him saying, 'Cousin, I have loved you all my life… those three words have my life in them' brilliant right, those words, she will make sure she creates that opportunity for her son to deliver them.
