Marriage to Justin

I just watched a clip talking about how insecure Jessica is about their marriage and how she wants a pre-nup (which I actually think is fine with people who make so much money), but in that pre-nup she wants a fidelity clause because she's so paranoid that Justin will cheat on her. She can't trust him enough going into this that she's insisting there be a fidelity clause saying that he will have to pay her $500,000 in the event that he does cheat on her. And she won't budge on having kids with him until he can prove that he'll be faithful to her for a long time--several years, in fact. She also apparently said that she's worried that when she gets fat during pregnancy, Justin will stray and cheat on her because she won't look attractive anymore. I'm sorry, but if you don't trust your intended husband this much before the marriage even happens, I'm not sure it's a good idea to get married in the first place. It seems like she's afraid it'll fall apart already and that doesn't seem like a good indication for their marriage. Don't get married if there's no trust--trust is the foundation of a good, solid relationship. Without it, everything can fall apart pretty easily. Just my opinion though. I hope that, if they do get married, they find a way to be happy for a long time.
