Husband troubles

Kristin
So I am noticing that my husband is pretty sensitive lately. He is a relatively light smoker and a heavy drinker. I have pleaded with him to quit smoking and significantly reduce his drinking but I am not seeing much progress. I enjoyed probably too much to drink prior to becoming pregnant and stopped cold turkey the day I found out I was pregnant. If we get into any kind of mild disagreement at all he blows his top and leaves the house to go to the bar to smoke and drink. Last night he told me I drive him to drink and smoke. Not sure what to do here. Anytime I raise my voice at all he flies off the handle. I can't take much more. What to do? Really not feeling loved and supported during this time that is supposed to be happy and draw us together. Married almost 8 years with our first baby.
