I have a 19 mo old and a 4 mo old, and let me just say that the transition from one to two kids is TOUGH... a LOT tougher than I expected it to be!! I will also say though, HANG IN THERE... after about 6 weeks when the younger baby gets bigger and starts sleeping a bit longer and such it does get MUCH EASIER! I had a few melt downs (i believe 3 in my first two weeks of being a mom of two) in which I sobbed to my husband that it was SO HARD and that I felt like I was never cut out to be a mom of two! But, with time, it gets a little easier, you grow to handle the new challenge, and you get used to it. Thankfully when I would cry to my husband he would tell me I was wrong and that I was a good mother, he has never ever told me I was a horrible mother, so I can't even imagine how you must feel right now.
I am so sorry about what is going on with your husband - what a terrifying experience to go through... I for one, would never tolerate that sort of violent behavior from my husband. I don't know precisely what I would do in your situation, but I can say that your man definitely has some issues he needs to work on... instigated or not, he should not ever be lashing out in such a violent way! Be careful and think about your daughters here...you might think he would never hurt them, but if he would act in such a way, can you ever be certain? Living in fear of your husband's unpredictable and violent behavior is not an okay way to live. You must have been terrified when it happened, and terrified that it will happen again even if you manage to work thing out. You might feel that you can handle living in fear, but can you imagine your daughters living in the same fear every day? Sometimes we accept things that should not be acceptable for ourselves, but its harder to accept those things for our children too.
As far as expecting him to help when he gets home, I don't think you are being unreasonable, but try to think about it from his side too... In my family I stay at home with our two boys while my husband works full time to support us and goes to school full time to finish his degree. I do have hard days some times (and every once in a while a day where he gets home and I say "TAKE THEM, I NED A BREAK TONIGHT!!!") I do expect him to help out when he gets home, but I try not to throw ALL OF EVERYTHING on his shoulders, because he is working SO HARD during the day that he needs his at home time to be a break from his hard day, so that he can regenerate and get back out there the next day. I expect him to help with diaper changes when he is home, and help to put the kids to bed and to entertain my toddler while I make dinner for us, but really I don't usually expect more than that. It is very hard being a stay at home mom, we do A LOT, and little children seem to take an infinite amount of patience sometimes and push our buttons all day. It can be easy to "unload" all the stresses of the day on your husband when he walks in the door, but if we do that, it will make him not want to ccome home to us at night and not look forward to it. He is out of the home working all day every day to support his family...it is our job to take care of our homes and our children as best as we can to make it a happy, welcome, and loving place that he want to support and protect with everything he has! If we make it a drag to come home to by nagging, fighting over stupid things, and acting like we are the only one doing a hard job to support our family, he will not enjoy coming home at the end fo the day, and he will start doing as your husband did and find excuses not to. I am NOT IN ANY WAY condoning his behavior, since I would have also been VERY upset and hurt if my husband felt he needed to lie to me in order to take some time for himself, for two reasons - one, that he lied, and two, that I had been treating him in such a way that he felt he needed to lie just to take some alone time with his buddies. I would be really examining my behavior that made him feel he needed to lie in order to avoid me. The Lie itself would be somethign that would have to be worked out - I expect full honesty from my husband, which is what I give to him, and because of that we trust each other fully...one lie would be all it would take to shatter that trust. That would be a large thing to work through for us.
I just read your post again to my husband, to see what he thought, and honestly in the second reading of it I noticed something really disturbing...you are stating so matter of factly what your husband did to you just TODAY and you are asking for advice not for what to do now that your husband treated you like that, but for how to handle adding a new baby to the family and not being a nag (which is why I answered those questions first). It seems to me that your husband's violent behavior is a normal occurence to you... maybe this last one was larger than usual, but I can tell by your post that you don't seem shocked by it. This is NOT ACCEPTABLE behavior. I grew up with a dad who is a wonderful guy, but he does loose control of himself every once in a while in anger after having his buttons pushed the wrong way. Usually he never hit us or my mom, but he would throw dishes, break doors, smash things, and once I pushed him so far when I was around 16 that he freaked out and literally dragged me up the stairs to my room by my hair, and hit me quite a few times. I was being a brat, but I did not deserve that. He was very very sorry for it afterwards (days after) and honestly I LOVE my dad and wouldn't trade him for anything, as these episodes were very (years in between them) infrequent and that episode when I was 16 was the worst one and the only time it ever escalated that far, but I swore after that that I would NEVER EVER tolerate that behavior from my own spouse. Losing control when you are angry is not ever okay and no one ever does anything that they don't greatly regret later. Being in a physically and mentally abusive relationship is not okay, its not normal, and its not healthy for your children to grow up in either. If i were you I would realy examine the type of realtionship you wanted vs. the relationship you have, and the things that you have done that could have caused it, as well as the things that he has done that are not acceptable. And really just think about your daughters and the women you want them to grow up to be, and the veiw of men that you want them to have, as well as the veiw of women that you want them to have. Would you feel okay if your daughters grew up and got themselves in a similar situation as you are in now? What would you tell them if they came to you and told you that their husband had just done to them what your has just done to you? Woudl you tell them to forgive him and try to win him back? Or would you tell them they needed to leave and find a better, more gentle man to raise their children with? Also do you want them to grow up and watch their mother be permissive with unacceptable behavior from men, and in turn accept that same behavior themselves as women and mothers? These are tough questions to answer, but you need to think of the future of your children and what is best in the long run, not just what is easiest in the short term. Choosing what is ultimately best for you and for your children is a difficult thing because it is often very difficult in the short term, but its always worth it and you are strong and have what it takes to make that decision and stick with it, regardless of what it may mean.
