Did this former cheater deserved this treatment?

I just read her update on reddit:

https://www.reddit.com/r/survivinginfidelity/comments/yozb12/my_husband_40_m_and_i_39_f_are_working_things_out/

- She cheats in 2002 with the guy's friend. She was 19 at the time. They were boyfriend and girlfriend.

- The guy forgives, she betters herself, hever cheated since, they get married later on and have 3 kids.

- 20 years later, this time the husband cheats with his co-worker but for different reasons, unrelated to her old cheating.

- The guy falls in love with his co-worker, he exchanges texts about traveling to Paris with her and leaving his kids, spends money on his affair (even steals and uses some of his wife's money) and takes his wife's meals and desserts to feed the woman

- Everything backfired in the end; his AP partner was using him for money. They're currently working things out. She's sounds upset on her post though.

Yes, she cheated first.. its fair
No, it isn't deserved

She went from feeling sorry for herself and guilt to now getting upset too after finding out he used her money for his affair, had imagine leaving her and his children to go to Paris and fed the woman her food.
