It's 90 days after a border hop according to Milk Tea. So she's got until the end of August. That's why she says "it's crunchtime", because she has just one more month before she next MUST travel. That car trip last time was clearly very uncomfortable for her because they immediately replaced the smaller car for one she could better fit in. She's not going to want to do that again, even in a bigger car. I suspect we'll find she flies somewhere at the end of August. Whether she returns or not will depend on whether Salah wants her back. I suspect he will just by virtue of everything (except his female companion) being upgraded since she arrived. Housing, car (we really don't know that he had the flash new car he conveniently sold before she first arrived there and no-one in his/her orbit can be trusted to be telling the truth), not having to work anymore, gym memberships where he can play pool with his male mates etc, all financed by his enormous fake wife. It all comes down to when the disadvantage of living with her exceeds the life upgrades he's currently enjoying.
According to people in the ME, she can border hop as often as she likes. It's very common practice and some people do it for years without issue. Unless she does something to really alert the authorities to to her actions (where they want her gone for good), they won't be batting an eyelid. Posts about authorities stopping her at the border by denying another visa, are about as annoying as posts about how much people think she weights.
