You dont know that.....can’t say it with authority.
Right back at you. Thomas Cromwell arranged a drumhead trial, wiped out most of the Boleyns, and ironically set the clock ticking on his own fall for his very real corruptions, after everyone else at court realized they could be next.
The Anne of Cleaves debacle provided the opportunity for his enemies to rid themselves of him.
Unrelated: Anne of Cleaves is my favorite of the wives. She's the only one who came out anything close to a winner. She could figure out which way the wind was blowing, and adjusted her views and conduct in a way that kept her alive and mostly prosperous. In fact she was quite popular.
That’s the point..no doubt Cromwell felt she was a liability to himself by that juncture
But it’s all speculation now
And scholars who study the body of evidence available today opinions tend to shift with cultural wind
Today with feminism and more specifically #metoo sentiment so called experts look at that Boleyn woman with a hoped for outcome they seek to justify
