It most certainly is a horrible dea. If Anni can provide even a shred of evidence that she contributed to the property then she easily has a claim to half of the sale price during litigation. Rob is banking on the fact that she's too far gone to try anything, but I think he's sorely mistaken. All it takes is for her to go to a single divorce attorney.
Personally, I think she did contribute, but Rob's fragile ego won't allow him to admit it. He coincidentally can't pay his mortgage on time after she left, but she didn't contribute a single cent? Yeah, I don't think that's a coincidence. Unless he really is just that retarded and wasted all his money on gambling and drugs bossmanrob style.
Also, I don't think anyone has pointed this out yet, but remember when he said that Joe Savage would be coming to visit him and they're either going to King's Island or Cedar Point? Now, tell me how the fuck this guy can afford an amusement park when he's reporting struggling so bad for cash that he just lost his house? Oh yeah, Savage is gonna be there which means Savage is probably gonna foot the bill. lol. Imagine that. Him simping so fucking hard for some smackhead loser that he not only flies out to his house but takes him to an amusement park too—probably all on his dime. What a fucknugget.
