The previous posts are describing a relationship built on emotional/psychological abuse. When Evans is around his wife, he has her under his thumb. When he isn't around, she will find ways to hit back at him. If I've got the details right, it goes something like this:
He says he wants an open relationship, and she says okay, despite what must be considerable misgivings. Given some time to think for herself (and without him there to influence her), she changes her mind and, for a change, tells him so directly. He is furious but cannot get her to bend, so he takes a drastic step and leaves for Thailand.
(This is common in abusive relationships- the abused will occasionally stiffen and put up a fight, at which point the abuser will either soften and make promises to 'be better' or ramps up the pressure.)
Free of his influence again, she starts leaking all kinds of messages and photos, and threatens divorce. He comes scrambling back to "fix" things. She starts taking his side and disavowing anyone who criticizes him, and helps him with videos and agrees to be photographed on vacation with him, etc.

If I'm understanding their situation at present, they are apart. So his only means of control at this point is financial, which is one reason why he must be panicking at the sight of his monetary support drying up. What is the worst part about giving up his 'activism' and going back to the 9-to-5 grind? That his wife will no longer have any incentive to hold back. And that she might have other photos and messages. If he thinks he'll have trouble getting any job better than dishwasher, it probably won't get any easier when everyone knows just how bad of a person he really is...
