Is it a one time thing?  I don’t know.

So what has he said about being drunk again?  What will keep him from doing it again?

What has he said about the next time when he is feeling bad about himself?  What will he do to deal with that?

What has he said about the next time he gets mad at you or the next time you tell him something that he does not like?  Will he retaliate again like that?  What more productive practices will he commit to instead?

Unless those reasons are *addressed* so when the next time one of those things happen then I won’t trust him.  What assurances can he give that it won’t happen again besides telling you that it won’t happen again?  He needs to have tools to deal with those situations, i.e. being drunk, feeling bad about himself, being resentful to you, etc.  Until he has non-destructive ways of dealing with life, then he may do it again.

Make sense?
