NOT wishing for his transformation

I read or heard somewhere that if there is someone we have trouble with we should not wish for their demise, but for their transformation.  I have an ex-husband who is trying to be a menace in my life – I know this will be considered a thought, but listing C’s is a long version of that.

At any rate, the thought/thought pattern I have that I think is problematic is that I wish he would just disappear. I do not wish for his transformation.  I wouldn’t not want to trust him now or ever in the future. I do not believe he will ever be truly transformed. I was already betrayed and lied to by him numerous times in the past, I do not want to do it again.  I’m not wishing anything good for him and I feel as if I should.
