I never have either. It was horrible living with him, even when it was OK because I was worried about when the horrible would arrive. There's nothing to miss. I went through a stage when I thought perhaps I hadn't loved him ever: there was undoubtedly a strong emotional bond, but I think I was mistaking powerful emotions related to drama for love. Now I'm not so sure that I never loved him, I think mixed in with all the rest I did, perhaps.
But I have never missed him once we seperated, and I'm not at all angry, I just have a huge relief that I'm not in the midst of it anymore. Literally every day, and no matter how bad that day is, I am grateful that in addition to the ups and downs of normal life which we all have to deal with, I am not burdened by living in that maelstrom. The scales have fallen from my eyes. Sometimes I miss the company of a loving, adult companion, but he was never that, so I'm missing what I think a companion should be, not him.
