She must have a fairly fickle breaking point/threshold though. If indeed she is primarily driven by the material comfort of her living situation, I think it is a little telling that she cheated on Subaruman when he was already providing her with a rather comfortable upper-middle class lifestyle where her only tangible complaint of any real substance was being dragged along to watch Marvel capeshit.Only if she finds a better deal. Think about it: right now she lives rent-free, doesn't have to work, doesn't have to have sex with Phil, gets a car she can drive whenever she wants, can let herself go and blimp up on potatoes, gets BIG, BLACK DICK on the side whenever she feels like it, and all she has to do is pop the occasional frozen meal in the microwave.
If King Tut comes by and says "I'll give you a million dollars a year to do absolutely nothing", then sure, she'd bolt. But realistically, any DSP replacement is going to demand more and provide less.
When the creditors (or the bankruptcy trustee, if they are that lucky) start imposing severe austerity measures on the disposable income at Casa Burnell, I think it will push her much closer to that breaking point. She already has her own phone on her own mobile plan, so who's to say she is not already fishing for a new soulmate.
