Unfortunately, the incident was vivid because he asked a lot of questions about what I was shredding and why. I hadn't realized he was drunk at that point (our other neighbours informed me yesterday).
I think that to a certain extent my move makes him sad. Not jealous, really, but he had told me that he wanted to buy or rent a house so he could get full custody of his daughter.
I think the big turning point in my life has been the realization that many critics aren't at all helpful. I used to think that any criticism could be constructive and a point at which to re-group or re-evaluate what I was doing. But now I recognize that sometimes I actually DO know what I'm doing.
