Am I being unreasonable to think this is not on?!

[Renaissance227]

I'm 32+2 today and although I don't have terrible mood swings I can get snappy with my DP over very little. He's currently drinking enough to sink a small ship most nights (and stinking of stale larger almost every day!) which is starting to irritate me so I snap at him a lot and get very short tempered with most things that he does. (Apparently he will stop drinking as much SOON but this is still not happening!)
Anyway, Last night I did just this after HE had had a long soak in a hot bath and he was asking me stupid questions about stuff (not pregnancy related!). I was tired and had had enough of pandering to him, BUT I got a mouthful from him about how I'm a "moody bitch" and should "sort it". I explained about pregnancy hormones etc and how I'm getting tired and have aches and pains all over but he just said this is not pregnancy related just me being a moody bitch who deserves no sympathy. He seems to think that pregnancy hormones just mean that you are either very happy or very sad and crying.

I am feeling totally deflated and horrible today.

(Also last night I had a horrible nightmare about him turning into a drunk/psycho who was determined to leave me and I woke up crying. When I told him what the dream was about this morning all he said was that's not scary. Why were you so upset?!)

This isn't reasonable behaviour from him is it?!

You are snappy because he's a lazy, selfish alcoholic. Best of luck with the future - you are going to need it.

OP, maybe you should ask for this thread to be moved to Relationships. There are lots of posters on there with experience of dealing with alcoholic partners. It's a tad more gentle then AIBU...less chance of bunfights.

Thank you CognitiveDissident. I might try there!

Sorry, but it sounds like he is an alcoholic. Drinking that amount every single day is a an alcohol problem. Things will not change until he gets help to give up the drink. It's not normal behaviour at all.
You are not snapping at him because you are pregnant you are snapping because his behaviour is selfish and unreasonable, and it's only going to get worse once baby arrives. Your dream about him leaving is quite telling, you sound scared that he will leave you, yet your life would probably be easier if he did leave as then you would have only you and the baby to care for. In most normal relationships your partner would be looking after himself at this stage and perhaps helping you out with your stuff too.
I would go out somewhere with him before he has a drink and have a serious conversation with him. Try to put your irritation over the results of his drinking to one side and speak to him about your concerns and the effect it's having on your relationship. Also explain about how difficult it will be once baby arrives and how you will need him to help out.
I wouldn't have the conversation if he has had a drink or at home though.
