Twistedmoon, just be safe.

That's most important. I'm sure you already know how it feels, but it can be soo very hard trying to cope with antisocials in a bad mood. Take my husband, for example. I just want to strangle him sometimes. Other times I do. What's really helped me is getting him to open up and talk to me about his decisions before he does something stupid and illegal which would get him into trouble later, and then try to enourage him to do something else. If he does get into a bad mood, I just let him vent, like he said.But I help him do it in a way that won't get him into more trouble or hurt himself. And I make sure to take time to myself too. If he starts stressing me out, I'll take it out on him, then there's just a vicious cycle of us driving each other nuts.
P.S. I did not have a knife, Michael!
