Happy New Year's

I'm pretty sure that I don't know who he is any more. What kind of person can do what he did and come home to his family? Doesn't it really mean that he is capable of being two different people at any given time. I'm confused, I am leaning towards seperating. I am unsure how to go about it all. I'm unsure how to end this being 6 months pregnant. I am unsure if ending this 14 year relationship will do any good. I am already so damaged by what he has done. Today when I opened his email, there staring back at me was an untitled email from her....I opened it. It was a general message sent to the whole department "HAPPY NEW YEAR'S EVERYONE! I hope this coming year is all that you want it to be." I wanted to barf. I wanted to write her back and say "thanks to you and my asshole husband this coming year will be everything I never wanted it to be. I express myself to him often throughout the day. He just responds that he loves me. He can't make it better. NOTHING can.
