Why is opie talking about being so miserable with his gf? It's not like he was married, he could have dumped her at any time.
Opie's girlfriend was Rick Delgado's (A TREE RIGHT THROUGH HER HEAD!) sister Sandy, and she was best friends with Jennifer. So Opie didn't want to break up with her, as her brother was a lead producer for the show, and she was friends with Anthony's wife and they would all hang out constantly. So part of the misery of their relationship was that Opie knew that Jennifer was setting up to divorce Anthony. And that Anthony hated Jennifer as well. But he couldn't talk to his girlfriend about any of this because she might give information to Jennifer that Anthony didn't want her to know.
So they would go on these weird double dates where Jennifer had privately told Sandy, "I want to leave Anthony and divorce him". And Anthony had told Opie, "I want to leave Jennifer or have her killed". And they would all awkwardly sit there knowing that the divorce was right around the corner. And all have to pretend that they all liked each other and everything was going great. But meanwhile Jennifer had already spoken to lawyers about how to get Anthony's money and had opened up another account in the bank to siphon Anthony's money into without him knowing.
Remember the time Anthony told the story where he tried to take out half of his joint savings account that he shared with his wife? Opie said "Now that you are separated you should check your joint account" and Anthony said "I'll just take half to be fair". And she had already drained the entire account leaving him with nothing completely behind his back. Jennifer hilariously used that money to book her and Opie's girlfriend a luxury cruise for a week or two in a deluxe cabin and they blew probably $40,000 on that vacation of Anthony's money without a second thought.
That ended up driving a huge wedge between Anthony and Opie, and as Anthony blamed Opie and Sandy as much as Jennifer or himself. And this was the first of many times where Jennifer would take five or six figures of Anthony's money and flush it down the toilet in a week of spending. Going all the way to today where Jennifer likely squandered $2.5million or more of Anthony's money and is now flat broke. I would not be surprised if Jennifer spent over $2million on vacations from the divorce settlement without saving any of it.
