LOL, one of my exes (not an alcoholic) threatened a couple of times to take me to court for this or that. I KNEW it was all hot air and empty threats because he didn't have the proverbial pot in which to urinate.
It's so nice when we can spot the BS with utter certainty.
The other thing I had observed about him during our time together was how he was always ranting he was gonna do this or that to "show" his ex-wife. He never did a thing. It was all noise. So I knew when he was making the same noises at me, it didn't mean a thing.
