They could try to make that case, but unless you were really trying to sabotage their R through direct actions, there's no way anyone would give that silly thought any credibility. As some might say, "That dog don't hunt."
Besides, if anyone is going to think that way, there's nothing we can do about it anyway. You can't control how other people think even when they're sane, so it's pointless to worry about what crazy people think. In my case, my xW already thinks the worst of me, so it wouldn't matter what she thinks about me after her third M eventually fails -- she's already done her worst.
We again have to focus on those things that are in our capacity to control.
