Well I think you did the right thing by going outside and cooling off because I think no matter what you did or said it wouldn't of gotten through or would of made things worse anyways. Hes not being very supportive at all which is never easy and pisses you off. There's really not much you can do in my opinion besides sitting him down and having a conversation on how you feel and say everything you have to say. If that dont work then you just go on with your sobriety and let nothing get in the way .
Im sorry you have to go through this im lucky my girlfriend doesn't drink but sometimes I didnt or dont get the support I want or need and get mad myself. But i cant change it so I just keep moving forward. Good luck just keep your cool and ur sobriety thats all you can do =)
