Do you think my partner or myself is in the wrong in this situation?? (maybe long, sorry.)?

You definitely shouldn't have packed up your children and drove after you had been drinking. I wouldn't do it if I've had even one drink. Also, if he reacts like that after another bout with liquor, you need to talk to him about not drinking it. After all, it was an isolated incident. Just make it clear that you expect an apology.
