I understand why Elizabeth is gambling with the trust fund money. She feels bought & paid off by Jason. He gave her the cash to do whatever she wanted to, for the kids, but she doesn't want to use it really. She wanted to be a single mother raising her kids, and she is one. She wants to give her kids everything in the world but it's hard to do that on a nurse's salary. Now, she absolutely could use the cash and send Cameron to camp or anywhere really. But- she hates that cash. By investing in something, she hopes to make money- in a way on her own- and she can send Cameron to camp using the profits of HER investment.
Nik is constantly trying to throw money in her face as a reason to be together. Jason did a payoff & ran away, with virtually zero contact for 2 years. Neither man has shown,lately, interest in her as a person, someone to love & cherish. Nik was an illicit affair. She loved Jason but it's not like he begged her to stay with him. Lucky, as disgusting as he is, wanted her. Maybe he wanted her because he's controlling, revenge, habit, love, or the need for her to mommy him. That's why, IMO, she wanted to be with him- the need to be needed. Now, she needs to cut the damn cord with both Brothers Grimm. I want her to smack Jason upside his head & knock some sense into that man.
