The challenge about Piecing is (and I think credit goes to ol' Jack Three Beans on this one) that nearly the entire skillset that was required to DB (and especially if there was infidelity involved) . . . is not only NOT applicable in Piecing, it's actually nearly the OPPOSITE of what's called for!!!
"Filling their love bank" and "speaking their love language," while there is OM/OW contact, is "pursuing." When you're piecing, it's REQUIRED, and you gotta have the patience of Job with it. That's just one example -- there are many, many more.
In general, most people when dealing with affairs are too EASY; and when piecing are too HARDAZZ.
