The sad part is, until he is truly ready to break it off 100% himself , the cycle will continue.... I hope he is ready to see the truth and be done with her for good.

2 of my brothers have gone thru situations with bad wife choices (more than once for both of them) and they went back & forth a few times before the final realization that it wasn't the way they wanted their future to look.

But they didn't hook up with quite such a loose or dangerous cannon..

one did get accused of abuse & rape by one of the wives - but she dropped it as it was a total lie.
