How can I deal with the anger problems I've gained from my soon-to-be husband?

I been having anger problems a lot lately. It only takes one word wrongly said to set me off. I use to not be like this until I got with my soon-to-be husband. I think his mood and rage/anger problems have rubbed off on me a lot. I don't get nearly as bad as he does, but I yell almost constantly and I can't seem to just stop. I have two young babies that have to hear this, and I don't want my girls growing up with a mommy like I have been lately. I just don't know how to get back to my old self.
